WILLIAM [I] "Taillebois" de Lancaster, son of GILBERT & his wife Goditha --- (-after 1166). An undated manuscript relating to Cokersand Abbey, Lancashire records that “Gilbertus [genuit] Will; qui quidem Willielmus fecit se vocari Willielmum de Lancaster...baronem de Kendale”[248]. “Willielmus filius Ranulphi” confirmed the foundation of St Bee’s priory, Cumberland by undated charter, dated to [1105/20], which refers to donations by “Willielmus filius Gilberti de Lancastria”[249]. "Willelmus filius Ranulfi" confirmed the donation of land "de Swartahof" donated by "Willelmus filius Gilberti de Lancastre" to St Bees by undated charter[250]. An undated manuscript relating to Cokersand Abbey, Lancashire names “Willielmum de Lancaster” as son of ”Gilbertus”[251]. A charter of King Henry II confirmed the donation to Furness by “Willilemum filium Gilberti” also named “primus Willielmum de Lancaster, baronem de Kendale, qui prius vocabatur de Tailboys”[252]. "Willelmus de Lancastre" donated property to Leicester, St Mary de Pré, with the consent of "Willelmi filii mei et hæredis et Gundredæ uxoris meæ", by charter dated to [1153/56][253]. "Willelmus de Lancastre" donated pasture rights in "feodum meum in Lonisdale et in Aumundernesse" to Leicester, St Mary de Pré, with the consent of "Willelmi filii mei et heredis et Gundree uxoris mee", for the souls of "…Gilberti patris mei et Godithe matris mee et Jordani filii mei et Margarete filia Comitisse", by charter dated to [1156/60], witnessed by "Willelmo filio meo et herede, Gundr fil Comitisse…"[254]. Lord of Kendale and Lonsdale in Westmoreland in 1166[255]. A charter of King Henry II records that “primus Willielmum de Lancaster, baronem de Kendale, qui prius vocabatur de Tailboys” married “Gundredam comitissam Warwic”[256].
[m firstly ---. No direct proof has been found of this supposed first marriage. However, assuming that Hawise, wife of Richard de Moreville, was the daughter of William de Lancaster, she must have been born from an otherwise unrecorded first marriage, given the estimated birth date of William’s known wife Gundred de Warenne.]
m [secondly] ([Jun 1153/1156]) as her second husband, GUNDRED de Warenne, widow of ROGER de Beaumont Earl of Warwick, daughter of WILLIAM [II] de Warenne Earl of Surrey & his wife Elisabeth de Vermandois [Capet] ([1120 or after]-after 1166). Guillaume of Jumièges records that ”Walerannus et Robertus...mater eorum” married secondly after the death of her first husband “secundo Willelmo de Warenna comiti Surreiæ” by whom she had “Willelmum tertium et duas filias” of whom “filiarum...primogenitam” married “comes Rogerus de Warwic”[257]. Robert of Torigny names "Gondrada sorore uterine Galeranni comitis Mellenti" as wife of "Rogero comite Warwicensi"[258]. An undated manuscript relating to Cokersand Abbey, Lancashire records that “Willielmum de Lancaster” married ”Gundredam prius comitissam de Warwyke”[259]. Her second marriage is confirmed by a charter of King Henry II which records that “primus Willielmum de Lancaster, baronem de Kendale, qui prius vocabatur de Tailboys” married “Gundredam comitissam Warwic” and that she was the mother of his son William[260]. Her marriage date is dictated by the death of her first husband, recorded in Jun 1153. "Willelmus de Lancastre" donated property to Leicester, St Mary de Pré, with the consent of "Willelmi filii mei et hæredis et Gundredæ uxoris meæ", by charter dated to [1153/56][261]. "Willelmus de Lancastre" donated pasture rights in "feodum meum in Lonisdale et in Aumundernesse" to Leicester, St Mary de Pré, with the consent of "Willelmi filii mei et heredis et Gundree uxoris mee", for the souls of "…Gilberti patris mei et Godithe matris mee et Jordani filii mei et Margarete filia Comitisse", by charter dated to [1156/60], witnessed by "Willelmo filio meo et herede, Gundr fil Comitisse…"[262]. Farrer has suggested that the wording of this last document indicates that the wife of William de Lancaster was the daughter of Countess Gundred rather than the countess herself, suggesting that the latter must have been "well advanced in years" at the time of the marriage and implying that she would therefore have been past child-bearing age[263]. It is correct that the wording of the document is curious as it appears inconsistent with both possibilities: if Gundred was "Comitisse", one would expect the first part of the document to read "Gundree Comitisse uxoris mee"; on the other hand, if she was Gundred the daughter, one would expect the subscription to read "Gundr fil Comitisse ux mee". The two names which are quoted above in the subscription list of the document dated to [1156/60] precede the subscribers who held religious positions. It would therefore be normal for them to be the same persons who are named in the body of the document, in the same order, giving their consent to the transaction. However, it is difficult to adopt an interpretation which contradicts the three different sources quoted above (Robert de Torigny, the undated manuscript, and the charter of King Henry II) which identify the countess as William’s wife.
