GURWENT [Gurvand], son of --- (-877).

Her parentage is deduced from the Annales Mettenses which names "Judicheil ex filia Heriospoii regis natus" when recording that he ruled jointly with "Alanus frater Pasquitani"[61]. Her marriage date is suggested on the assumption that she was the same daughter of Erispoe who was earlier betrothed to Louis, son of Charles II "le Chauve" King of the West Franks (see above), but this is not certain. Gurwent & his wife had [two] children:

a) JUDICAËL (-killed in battle [1 Aug/8 Nov] 888). Comte de Rennes. Regino records that "Iudicheil, ex filia Herispoii regis natus" ruled Brittany jointly with "Alanus frater Pasquitani" after the death of Pascwethen in 876, and his death in battle against the Vikings[62]. He succeeded his father in 876 as joint Duke of Brittany, ruling jointly with Alain Comte de Vannes. Regino records disputes between "Alanum et Iudicheil duces Brittonium" in 890[63], which indicates that the date of his death recorded in the previous passage in the same source may not be accurate.

b) [daughter . The primary source which confirms her parentage and marriage has not yet been identified. Borderie suggests that Judicael Comte de Rennes was the grandson of Duke Gurwent, but he does not cite any primary source which supports his reasoning[64].
