; Per Genealogics:
     “Dietrich was born about 990, the son of Dedi I, Graf im Hassegau, and Thietberga von Haldensleben. He was Graf von Wettin, from 1015 Graf im Schwabengau, from 1017 Graf von Eilenburg und Brehna, Graf im Hassegau und im Gau Siusili, and from 1032 the first Wettin margrave of the mark of Lusatia (Lausitz). About 1016 he married Mathilde von Meissen, daughter of Ekkehard I, Markgraf von Meissen, and Schwanhild/Suanehild von Sachsen. They had six sons and a daughter Hidda. Hidda married Spytihnev II, duke of Bohemia; in 1084 their son Swatobor Friedrich would become patriarch of Aquileia.
     “At Christmas 1009 at Pöhlde King Heinrich II (the future emperor) enfeoffed Dietrich with all his father's fiefs, including the northern Hassegau and his father's share in the district of Zörbig. In 1017, after the death of his uncle Friedrich I von Eilenburg, the emperor enfeoffed him with his uncle's county and rights in the district of Siusili.
     “
Together with his brother-in-law Hermann, Markgraf von Meissen, and the emperor's chamberlain Friedrich, in 1018 Dietrich was a witness to the Peace Treaty of Bautzen, which ended the war between Heinrich II and Boleslaw I Chrobry, king of Poland, that had lasted since 1002. When war was renewed by Boleslaw's son Mieszko II Lambert, Dietrich organised the defence against Poland. According to the _Annalista Saxo_ of 1030 it was only Dietrich who seriously resisted Mieszko and eventually forced him to pull back. From 1032 he was margrave of Lusatia.
     “On 19 November 1034 Dietrich was killed by the followers of his brother-in-law Ekkehard II, who succeeded him as margrave of Lusatia.”.⁵

and as ”Dedo II. (Lausitz)” at Wikipedia (De.)^15,16,17 He was Margrave of Eilenberg and the Saxon Ostmark.¹

; Per Genealogics:
     “Dedi was the second son of Dietrich II, Graf im Hassegau, Graf zu Brehna, and Mathilde von Meissen. He was the margrave of the Saxon Ostmark (also called Lower Lusatia) from 1046 and margrave of Meissen from 1069.
     “Dedi inherited the Ostmark from its last dynast, the childless Otto II, because he had married his sister Oda, daughter of Thietmar II, Markgraf von der Lausitz. Oda was herself the widow of Wilhelm III, Graf von Weimar, and mother of Wilhelm and Otto, margraves of Meissen successively. Dedi and Oda had three children of whom Adelheid would have progeny, marrying Ernst 'the Brave', margrave of Austria.
     “When his stepson Otto died in 1067 he was succeeded as margrave of Meissen by Ekbert I, Graf von Braunschweig. However in 1069 Dedi married Otto's widow Adela of Louvain, daughter of Lambert II, comte de Louvain, and Oda of Lower-Lorraine, and in her name he claimed the Meissen march. In doing so, Dedi was challenging the royal prerogative in the marches. With him in his revolt was Adalbert, Graf von Ballenstedt, who raided the monastery of Nienburg, a foundation of the family of Dedi's first wife. Adela of Louvain for her part aggressively supported her husband, so much so that the medieval chronicler Lambert of Hersfeld was compelled to call her a _saevissima uxor._ Adalbert, archbishop of Hamburg-Bremen, one of the regents for the young king Heinrich IV, frustrated the Thuringian rebels and preserved the peace in Thuringia and Meissen. Dedi was confined to Lusatia, where he was succeeded by Dedo III, his eldest son from his first marriage.
     “Dedi died in October 1075. By Adela of Louvain he had two sons, Heinrich who later ruled both Lusatia and Meissen, and Konrad, who died in battle with the Wends. Neither son left offspring.”.⁷

     Gero II (c. 975 – 1 September 1015 at Krosno Odrzan'skie) was the eldest son of Thietmar, Margrave of Meissen, and Suanhild the daughter of Herman, Duke of Saxony. He was therefore probably a grandson of Hidda and Christian of Thuringia and named for his great uncle Gero the Great. He succeeded his uncle, Hodo, as Margrave of the Saxon Ostmark including Mark Lausitz (Lusatia) in 993 upon the death of Hodo, Margrave of the Saxon Ostmark.
     Gero was created Count of Hassegau in 992, just a year before becoming margrave. He died in his territory in battle with a Polish army of Boleslaw I in Gau Diadesi and was buried in his family's monastery of Nienburg. He was survived by his wife Adelaide (Athelheidhe) and one son, Thietmar, who succeeded him.

     "Thibaut, known as Thibaut 'le Bon', was count of Blois from 1151 to 1191. He was the son of Thibaut IV-II, comte de Blois et Chartres, comte de Champagne, and Mathilde von Kärnten. Although he was the second son, Thibaud inherited Blois (including Chartres), while his elder brother Henri inherited the more important country of Champagne.
     "Thibaut first married Sibylle de Château-Renaud, which made him lord of Châteaurenault. The marriage did not result in progeny. About 1164 he married Alice de France, daughter of Louis VII, king of France, and his first wife Eleanor de Poitou, duchesse d'Aquitaine. Of their seven children Louis, Marguerite and Isabelle would have progeny. Isabelle was left the county of Chartres (alienated from Blois) and the lordship of Châteaurenault by her nephew Thibaut VI, son of her brother Louis I.
     "Thibault V and Alice had a happy marriage. His sister Alix de Blois, wife of King Louis VII, later regent for her son Philippe II, described them as 'a good, amiable couple'. Thibault lived primarily in Chartres and had its city walls renovated. After joining his brother Henri and number of other nobles in opposing the young king Philippe II August, he reconciled with the king and supported him on the Third Crusade. He arrived in the Holy Land in the summer of 1190, and died on 20 January 1191 in the siege of Acre."²

     "Thibaut V de Blois, dit le Bon (1130 † 1191, fut comte de Blois, de Châteaudun et de Chartres de 1152 à 1191. Il était fils puîné de Thibaut IV le Grand, comte de Champagne, de Blois et de Chartres, et de Mathilde de Carinthie.
Origine
     "La famille de Blois était alors puissante : un oncle, Etienne, avait été roi d'Angleterre de 1135 à 1154, un autre oncle, Henri, fut évêque de Winchester en 1129 puis légat du pape pour l'Angleterre en 1138, une sœur, Adèle, reine de France ; quant aux trois frères de Thibaut, ils furent respectivement comte de Champagne (Henri), évêque de Chartres, archevêque de Sens et de Reims, cardinale et légat du pape (Guillaume) et seigneur de Sancerre (Étienne).
Biographie
     "Son père, Thibaut IV, mourut le 10 ou le 12 janvier 1152 : les Obituaires de Sens Tome II, Eglise cathédrale de Chartres, Obituaire du xii siècle confirment que Thibaut V et sa mère, Mathilde, firent à cette occasion une donation pour le salut de son âme et que le comte fut enterré à Lagny.
     "Thibaut V, devenu comte de Blois et de Chartres, suivit la politique paternelle des dernières années et fut fidèle au roi de France Louis VII, qui le nomma sénéchal de France. Il succéda à Raoul de Vermandois et fut le dernier à porter ce titre, ce qui ne l'empêcha pas, en 1159, de sceller un accord avec le roi Henri II d'Angleterre pour attaquer la région de Beauvais contre Louis VII. L'année suivante, il était de nouveau du parti du roi de France, aux côtés duquel il resta lors de la coalition de 1173 qui vit Louis VII s'allier aux enfants d'Henri II, Henri, Richard et Geoffroy, qui, encouragés par leur mère, s'étaient rebellés contre leur père.
     "Après la mort de Louis VII, alors que le nouveau souverain, Philippe-Auguste, maintenait une excellente relation avec les fils d'Henri II d'Angleterre, notamment Henri et Geoffroy, Thibaut se joignit un temps à son frère aîné, Henri, et à Philippe Ier de Flandre, qui s'opposaient au jeune roi à propos du comté d'Artois et d'autre terres de Flandre qui faisaient partie de la dot de l'épouse de Philippe-Auguste, Isabelle de Hainaut mais à la mort d'Henri, Thibaut se rapprocha de son beau-frère et neveu par alliance, dont il devint, à compter de 1180, un fidèle soutien, de même que son frère, le cardinal Guillaume.
     "Thibaut et Étienne accompagnèrent Philippe-Auguste à la troisième croisade. Thibaut arriva en Terre sainte à l'été 1190 et mourut le 20 janvier 1191, de la dysenterie, lors du siège d'Acre, de même que son frère, Étienne de Sancerre.
     "Il est inhumé dans l'Abbaye de Pontigny.
     "Thibaut vécut principalement à Chartres, dont il fit rénover les murs. Le 26 mai 1171 à Blois, il envoya au bûcher 31 hommes, femmes et enfants appartenant à la communauté juive de la ville, condamnés à mort pour crime rituel (1re attestation d'une condamnation à mort pour accusation de meurtre rituel)1,2.
Union et descendance
     "Il avait épousé en premières noces Sibylle de Château-Renault, qui lui laissa ce fief mais dont il n'eut pas d'enfants, puis, en 1164, la capétienne Alix (1150 † 1195), fille de Louis VII, roi de France, et d'Aliénor d'Aquitaine. Cette dernière lui donnera sept enfants et assurera la régence du comté de Blois au départ de son mari à la croisade, puis, à la mort de celui-ci, au nom de leur fils mineur, Louis.

Biography
     "He was son of Theobald II of Champagne and Matilda of Carinthia.[2] Although he was the second son, Theobald inherited Blois (including Chartres), while his elder brother, Henry got the more important county of Champagne.
     "He first married Sybil of Chateaurenault, which made him jure uxoris Lord of Chateaurenault. Next, in 1164, he married Alix of France, daughter of Louis VII of France and his first wife, Eleanor of Aquitaine.[3]
     "According to medieval Jewish sources, in 1171 Theobald was responsible for orchestrating the first blood libel in continental Europe. His alleged Jewish mistress Pulcelina of Blois unsuccessfully attempted to prevent him.[4] As a result of a church-sponsored trial, 30 or 31 members of the Jewish community were burned at the stake.[5]

     "Alice or Alix was born in the summer of 1151, the second daughter of Louis VII, king of France, and his first wife Eleanor de Poitou, duchesse d'Aquitaine. She was named after her aunt Petronella de Poitou, who was also called 'Alix'. The birth of a second daughter to Eleanor and Louis instead of a badly needed son was one of the final nails in the coffin of their marriage. Her parents were soon divorced, although the princesses were declared legitimate, and the custody of the young Alice and her sister Marie was awarded to their father. Their mother Eleanor left the French court and married King Henry II of England. King Louis also remarried twice.
     "About 1164 Alice became the second wife of Thibaut V, comte de Blois, son of Thibaut IV-II, comte de Blois et Chartres, comte de Champagne, and Mathilde von Kärnten. Her sister Marie married Thibaut's elder brother Henri. Alice served as regent when her husband left for the east, and since their son was underage, she continued as regent for several years after Thibaut's death in 1191. Alice and Thibaut had seven children of whom Louis, Marguerite and Isabelle/Elisabeth would have progeny.
     "Alice died after 1195, probably in 1197 or 1198."⁴

     "Alix of France (July–August 1150 – 1197/1198) was countess consort of Blois by marriage to Theobald V, Count of Blois. She was regent of Blois during the absence of her spouse in 1190-1191, and regent during the minority of Louis I, Count of Blois from 1191 until 1197.
Life
     "Alix was the second daughter born to King Louis VII of France and Duchess Eleanor of Aquitaine,[1] and was named after her aunt Petronilla of Aquitaine, who was also called "Alix". The birth of a second daughter to Eleanor and Louis instead of a badly needed son was one of the final nails in the coffin of their marriage. Her parents' marriage was annulled in 1152, barely a year after Alix's birth. She and her sister, Marie, were declared legitimate, and the custody of the two girls was awarded to their father. Eleanor soon after left the French court and married Henry II, Duke of Normandy, who later became King of England.
Countess of Blois
     "In 1164, Alix married Theobald V, Count of Blois,[2] who had previously attempted to abduct Alix's mother to force her into a marriage with him. Her older sister, Marie, married Theobald's brother, Henry.
     "Alix served as regent of Blois for seven years. When her husband left for the East in 1190, she was appointed regent to serve during his absence. When he died in 1191 and was succeeded by their minor son, Alix continued to serve as regent, this time during the minority of her son Louis I. She governed until 1197.
     "Alix died in 1197/98.

     "Alix de France ou Adélaïde de France ou Aélis de Blois (1151 † 11 septembre 1198), fille du roi Louis VII de France (1120 - 1180) et de sa première épouse Aliénor d'Aquitaine (1122 - 1204)1, fut comtesse consort de Blois par son mariage avec Thibaut V de Blois. Elle fut régente du comté pendant l'absence de son époux en 1190-1191, ainsi que pendant la minorité de leur fils, Louis Ier, de 1191 à 1197.
Biographie
     "Alix était la deuxième fille du roi Louis VII de France et de sa première femme, la duchesse Aliénor d'Aquitaine. Elle fut baptisée ainsi en hommage à sa tante maternelle Pétronille d'Aquitaine, dont le deuxième prénom était Alix et qui avait suivi Aliénor à la cour de France.
     "La naissance d'une deuxième fille, au lieu du fils et héritier tant espéré, sonna le glas du mariage de Louis et Aliénor, déjà fragilisé : en 1147, le couple avait pris part à la deuxième croisade, qui devait se conclure par l'échec devant Damas en 1148, ce qui, joint à d'autres différends, contribua à éloigner les deux conjoins, qui regagnèrent la France séparément en 1149. Leur mariage fut annulé en 1152 pour consanguinité, un an à peine après la naissance d'Alix. Elle et sa sœur aînée Marie furent reconnues comme légitimes et la tutelle des deux jeunes princesses fut confiée à leur père. Aliénor quitta la cour peu après et épousa en secondes noces Henri II, duc de Normandie et futur roi d'Angleterre.
     "Les différents remariages de ses deux parents firent d'Alix la demi-sœur du roi Philippe-Auguste de France mais aussi des rois d'Angleterre Richard Cœur de Lion et Jean Sans Terre.
Comtesse de Blois
     "Après la séparation de ses parents, son père, Louis VII, épousa en 1154 Constance de Castille, qui mourut en 1160 en mettant au monde sa deuxième fille. Toujours en quête d'une descendance masculine susceptible de lui succéder, Louis VII se remaria la même année avec Adèle de Champagne1, promettant du même coup ses deux filles aux frères de sa nouvelle femme.
     "En 1164, Alix épousa Thibaut V le Bon, comte de Blois et de Chartres1, veuf de Sibylle de Châteaurenault, qui avait autrefois tenté d'enlever sa mère, Aliénor, pour la forcer à l'épouser. Sa sœur aînée Marie épousa le frère aîné de Thibaut, Henri.
     "Alix fut régente de Blois pendant sept ans. Lorsque son mari partit pour l'Orient pour la troisième croisade, en 1190, elle fut désignée pour gouverner en son absence. Lorsqu'il mourut de dysenterie en 1191 au siège d'Acre, aux côtés de son frère, Étienne de Sancerre, elle continua de gouverner au nom de son fils mineur, Louis, et ce, jusqu'en 1197, un an avant sa mort, survenue le 11 septembre 1198.
     "Elle fut inhumée en la cathédrale Saint-Étienne de Meaux.
Descendance
     "Thibaut et Alix auront sept enfants :
1. Thibaut, mort jeune ;
2. Louis, comte de Blois, de Chartres et de Clermont ;
3. Henri, mort jeune ;
4. Philippe, mort jeune ;
5. Marguerite (1170 † 1230), comtesse de Blois et de Châteaudun, mariée vers 1183 avec Hugues III d'Oisy, vicomte de Cambrai († 1189), puis vers 1190 avec Othon Ier, comte de Bourgogne († 1200)1, et enfin avec Gautier II d'Avesnes, seigneur de Guise († 1246) ;

; Per Genealogics:
     "Gaucher V de Châtillon was born about 1249, the son of Gaucher IV de Châtillon and Isabeau de Villehardouin. In 1276 he married Isabelle de Dreux, dame de Nesle-en-Tardenois, daughter of Robert I de Dreux, vicomte de Châteaudun and Isabeau de Villebéon, dame de la Chapelle. Isabelle died in 1300 and in February 1301 Gaucher married Helisende de Vergy, daughter of Jean I de Vergy, sire de Fouvent, de Champlitte et d'Autrey, and Marguerite de Noyers. After Helisende's death in 1312, Gaucher married Isabelle de Rumigny, heiress of Rumigny, Florennes and Boves. Gaucher was the father of seven children, of whom four sons and two daughters would have progeny.
     "Gaucher was constable of France under five successive kings of France: Philippe IV, Louis X, Jean I, Philippe V, and Charles IV. During Philippe IV's campaign of 1303 to win Flanders back from the Flemish rebels led by Wilhelm of Jülich, Gaucher, as constable of France, was with the small garrison of the town of St. Omer besieged by the much larger force of Wilhelm of Jülich. The French advanced out of St. Omer to give battle, and fought the Flemish to a stalemate which forced them to abandon their attempt to take the town.
     "Gaucher made a famous intervention in the Regency Council convened a few weeks after the death of Louis X on 5 June 1316. Louis' consort Clemence was pregnant, making it impossible to know Louis' successor until the time the child was born. If the child were a son, he would succeed Louis as king; had the child been a daughter, there would be a question between Louis' (eldest) daughter Jeanne and his next brother Philippe. In July 1316 Gaucher wrote:
     "'In truth, it would be madness to allow a girl to ascend the throne! Can you see a woman or damsel, menstruating each month, large with child each year, commanding armies? And reigning over her vassals, when she cannot even control the passions in her nature? No, I cannot see it, and I say it to you, France is too noble kingdom to fall to the female line and be given over to a girl. The lilies will not slip away!'
     "A little over a hundred year later Jeanne d'Arc stood beside Charles VII at his coronation on 17 July 1429, and not quite 250 years later Elizabeth I ascended the throne of England in 1558. In the event, Clemence's child was a son, who reigned for five days as Jean I, and was succeeded by Philippe V, brother of Louis X.
     "Gaucher was lord of Crécy, and in 1290 he became lord of Châtillon-sur-Marne by exchange. However in 1303 a new agreement allotted to him the countship of Porcean, while Châtillon reverted to the domain of the counts of Champagne. His château of Porcean on the river Aisne, near the town of Bethel, was given to him by Philippe IV in 1308. By his first marriage with Isabelle de Dreux, widow of Thibault II, duke of Lorraine, Gaucher obtained the town of Neufchatel in Lorraine; he minted his own coins there, and at Ive on the Moselle, near Nancy.
     "Gaucher died in 1329.

     “Gauthier V, comte de Brienne, was born in Brienne-le-Château, the son of Hugues, comte de Brienne, conte di Lecce, and Isabelle de La Roche-sur-l'Ognon, heiress of Thebes, daughter of Guy I de La Roche-sur-l'Ognon, duke of Athens. He was the heir of the Brienne claim to the kingdom of Jerusalem and of Cyprus, as well as to Taranto and Sicily.
     “Gauthier V spent his youth as a hostage in Sicily, in the castle of Agosta. On the death of his father Hugues in 1296, Gauthier inherited the titles of Count of Brienne, Conversano and Lecce. Like his father, he took up arms in the service of Naples, but was captured in an ambush at Gagliano in 1300. He was freed in 1302 with the signing of the Treaty of Caltabellota.
     “Before October 1305 Gauthier married Jeanne de Châtillon, daughter of Gaucher V de Châtillon, seigneur de Châtillon, comte de Porcean, and Isabelle de Dreux, dame de Nesle-en-Tardenois. Gauthier and Jeanne had two children: Gauthier VI de Brienne, his successor as count of Brienne and Lecce and lord of Argos and Nauplia, as well as the titular duke of Athens; and Isabeau de Brienne, who married Wautier d'Enghien and succeeded her brother on his death.
     “The death of his mother's first cousin Guy II de La Roche in 1308 brought Gauthier V the duchy of Athens. There he found himself hard pressed by the despot of Epirus, the emperor Andronicus II and the lord of Vlachia. In 1310 he hired the Catalan Company, then ravaging the Byzantine empire, to fight the Greeks encroaching on his territory. After the Company had successfully reduced his enemies, he attempted to expel it from Athens with its soldiers' pay in arrears. When the Company refused this, Gauthier marched out with a strong force of French knights from Athens, the Morea and Naples, and Greek foot soldiers from Athens. Gauthier's army met the Catalans at the Battle of Halmyros on the river Cephissus in Boeotia on 15 March 1311. The Catalans won a devastating victory, killing Gauthier and almost all of his chivalry, and seizing his duchy of Athens, excepting only the lordship of Argos and Nauplia. His son Gauthier VI de Brienne succeeded him in all his titles; the Catalan Company nominated one of the surviving knights, Roger Deslaur, as its leader and new duke of Athens by conquest.”.¹⁴

; Per Periphery of France: Outremer: "An interesting episode in the history of Athens was: the seizure of Athens by the Catalan Company in 1311. This was a mercenary band from Aragón that had been fighting for the Emperors of Romania. They mutinied and ravaged the area, ending up at Athens, where the Duke Walter [Gauthier V] hired them in 1310. They then murdered Walter in 1311 and took over the Duchy. Before long, sons of King Frederick II of Sicily, brother of King James of Aragón, succeeded as Dukes, but then sovereignty began to be exercised by Kings of Sicily themselves, starting with Louis. The Vicars-General of Athens have what usually look like Spanish names and so must largely be of Aragonese derivation.“.² GKJ-20.
