; Complete Peerage 10 (1945): 796, footnote k (sub Richmond) states that
Guy de Thouars, 3rd husband of Constance, Duchess of Brittany (died
1201), "never styles himself Earl of Richmond and it is clear that he
never had the Earldom."

The historian, J. Everard, however, states the following in her book,
Charters of Duchess Constance of Brittany and her Family (1999), pg.
137:

"During his marriage to Constance, the title was ‘Guido de Thoarcio,
dux Britannie, comes Richemondie' (Gu 2,3). As regent (from c.
mid-1203 to 1213, the title was, ‘Guido de Thoarcio comes Britannie'
(Gu5-9, 11-14, 16, 18, 19, 21-3, 25, 27, 28), conforming with the
practice of the French royal chancery, and not making any claims
regarding Richmond.")."

The reference "Gu 2,3" refers to two charters cited elsewhere in
Everard's book.

C.P. 10: 797 further states that after the death of Duchess Constance
in 1202, Guy de Thouars served as regent until 1213, when his
daughter, Alice, married Pierre de Braine. "He then disappears from
history, and the date of his death is not certainly known."

According to various sources I've consulted, it appears that the
subsequent history of Guy de Thouars is known. I find that in Oct.
1203, he was granted the castles of Chemillé and Brissac by King
Philippe Auguste of France. He died at Chemillé in Anjou 13 April
1213, and was eventually buried at Villeneuve. In addition to his two
daughters by Duchess Constance, he was survived at his death by his
second wife, Eustache, and two children by that marriage, Pierre
[seigneur of Chemillé, Mortagne, and Brissac] and Thomas.

Thouars and his children:

; Boyer (2001, pp. 2-3): [quote] Head of the army under King Richard I in Normandy in 1195, he was Sheiff of Rutland and many other counties in the period 1196-1199, and served as an itinerant justive in 1199 and on several occasions under King John. He served as Sheriff of Buckinghamshire and Bedfordwhire in the first year of the reign of King John. Having been forced to give his son John to King John as a hostage in 1201, he was a member of the moderate or middle section of the baronage in the conflict between King Johyn and the barons, remaining in attendance on the king until going over to the extreme party upon their taking possession of London on 24 May 1215. Going with them to Runnymede, he was elected a Magna Charta surety in 1215, and then withdrew to Belvoir. Although he was excommunicated by name by the Pope, along with de Quency and Mowbray, as a result of Runnymede, he refused to attend the Hounslow tournament on 6 July 1215.

He was prevailed upon to return to service in the fall, and was placed in charge of Rochester, but was forced to surrender it to John after a gallant defnse lasting from 11 Oc.t to 30 Nov. 1215, and was through into prison, narrowly escaping haning.

In 1216, upon payment of a fine of 6,000 marks (£4000), he was released and regained his lands. He did homage to King Henry III, was entrusted with Sleaford Castle and a command at the battle of Lincoln of 19 May 1217, which earned him high favor. In 1219 and 1225 he served again as an itinerant justice. [end quore]⁸
