GUILLAUME [I] "Talvas" de Ponthieu, son of ROBERT de Montgommery "de Bellême" Sire d'Alençon, Comte de Ponthieu, Earl of Shrewsbury & his wife Agnès de Ponthieu (-30 Jun 1171). His parentage is given by Orderic Vitalis[1240]. He succeeded his father [4 Mar 1106/1110][1241] as Comte de Ponthieu. "Wilelmus comes Pontivi" confirmed the donation of the church of Saint-Léonard de Bellême to Marmoutier by charter dated to [1112/14][1242]. Henry I King of England restored Comte Guillaume to his father's lands in Normandy in Jun 1119[1243]. He resigned Ponthieu [before 1129] in favour of his son Guy: Guillaume of Jumièges records that "Willelmum Talavatium" married "Ala...quæ fuerat antea uxor ducis Burgundiæ" [incorrect], and had "duos filios et totidem filias" of whom "filiorum primogenitus Wido" was made "patre vivente...comes Pontivi"[1244]. "Gulielmus comes Pontivorum" donated property to the abbey of Saint-Sauveur-le-Vicomte for the souls of "his predecessors earl Roger and Mabel his wife, count Guy and Adda his wife, his father Robert de Belesmo and his mother Agnes and…Ela his wife and of their sons two of them called Robert and two William and two Enguerrand and Mabel his daughter" by charter dated 1127[1245]. Robert of Torigny records that Henry II King of England granted "castrum Alenceium et Rocam Mabiriæ" to "Willermus Talavacius comes Sagiensis et filius eius Johannes et iterum Johannes nepos eius filius Guidonis primogeniti sui comitis Pontivi" in 1166[1246]. Robert of Torigny records the death in 1171 of "Guillermus Talavercius comes Pontivi" and the succession of "Johannes nepos suus…ex Guidone primogenito suo"[1247]. The Obituaire of Saint-Martin de Séez records the death 30 Jun of "Guillelmus Pontivorum comes"[1248].The necrology of the monastery of Ouche records the death "30 Jun" of "Willelmus comes Talevat"[1249].
[m firstly ---. The name of Guillaume´s supposed first wife is not known. This first marriage is strongly suggested by the marriage date of Guillaume´s daughter Clémence. She is named in Jul 1128 with her son "Gaufrido primogenito" (see below). The addition of the word "primogenito" suggests that there was at least one other younger child at that date. This would place her marriage in late 1125 at the very latest. It is extremely unlikely, therefore, that she could have born from Guillaume´s marriage to Hélie de Bourgogne, the death of whose first husband is recorded in late Apr 1112. The other indication is the unlikelihood that Hélie de Bourgogne could have had eleven children by her second husband, considering her own estimated birth date.]
m [secondly] ([late 1112/1115]) as her second husband, HELIE de Bourgogne, widow of BERTRAND de Toulouse Count of Tripoli, daughter of EUDES I Duke of Burgundy [Capet] & his wife Sibylle de Bourgogne [Comté] ([1080]-28 Feb 1141). She is named by Orderic Vitalis, who also records her parentage, her two marriages and the names of her eldest sons by each marriage[1250]. Guillaume of Jumièges records that "Willelmum Talavatium" married "Ala...quæ fuerat antea uxor ducis Burgundiæ" [incorrect], and had "duos filios et totidem filias"[1251]. "Gulielmus comes Pontivorum" donated property to the abbey of Saint-Sauveur-le-Vicomte for the souls of "…Ela his wife…" by charter dated 1127[1252]. "Guido comes Pontivi" donated property to Cîteaux with the consent of "pater eius Willelmus comes…et mater eius Hela" by charter dated 18 Dec 1139[1253]. "Wido comes Pontivii" confirmed freedoms over his lands, with the consent of "patris mei Willermi et domine Ele matris mee, fratris mei Johannis et uxoris mee Ide et filii mei Johannis" by undated charter[1254].
