Name: Constance de Brittany
Change Date: 7 JAN 2012
Conan IV had an only child, a daughter Constance, who married first Geoffrey, a younger son of Henry II of England who was thus acknowledged as Earl of Richmond and Duke of Brittany, then Ranulf, Earl of Chester, who styled himself Earl of Richmond and Duke of Brittany too.
She divorced Ranulf in 1199 and took a third husband, Guy de Thouars, who ran the Richmond estates, but may not necessarily have been recognized as Earl of Richmond.
Guy sided with the King of France against King John of England in 1203, whereupon his Engl ish lands were forfeited, after which the question as to whether he enjoyed recognition as Earl hardly arises. [Burke's Peerage, p. 2402]
