It will have been noticed that in this pedigree I assign to Gervase a brother Alan. I do so on the strength of a charter of Archbishop Theobald, late in the reign of Stephen, to Holy Trinity, witnessed _inter alios_ by "Gervasio de Cornhill et Alano fratre ejus,"[912] also of a charter I have seen (Duchy of Lanc., _Cart. Misc._, ii. 57), in which the first witness to a charter of Gervase is Alan, his brother. The "Roger fitz Alan" for whom I suggest an affiliation to this Alan occurs among the witnesses to a grant made by Ralph, and witnessed by Reginald de Cornhill.[913] This suggests such paternity, and his name, Roger, would then be derived from Roger, his paternal grandfather. We have here, at least, another clue which ought to be followed up, for Roger fitz Alan is repeatedly found among the leading witnesses to London documents of the close of the twelfth and beginning of the thirteenth centuries, his career culminating in his appointment as mayor on the death of the well-known "Henry fitz Ailwin" in 1212.[914]
