[314] Robert, natural son of Henry I. by Edith (afterwards married to Robert d'Oilli of Oxford), and uterine brother, as Mr. Eyton observes (_Addl. MSS._, 31,943, fol. 115), "to Henry d'Oilli of Hook-Norton." He appears in connection with Devonshire in the Pipe-Roll of 31 Hen. I., and is probably identical with Robert "brother" of Earl Reginald of Cornwall (_vide ante_, p. 82). He is mentioned as present (as "Robert fitz Edith") at the siege of Winchester, a few weeks later (_Sym. Dun._, ii. 310), and he was among the witnesses to the Empress's charters (Oxford, 1142) to the earls of Oxford and of Essex, and to her charter (Devizes) to Geoffrey de Mandeville the younger (_vide post_). He subsequently witnessed Henry II.'s charter (? 1156) to Henry de Oxenford (_Cart. Ant._ D., No. 42). See also _Liber Niger_. Working from misleading copies, Mr. Eyton wrongly identifies this Robert "filius Regis," as a witness to three charters of the Empress, with a Robert fitz Reg_inald_ (de Dunstanville) (_History of Shropshire_, ii. 271).
[315] Robert fitz Martin occurs in the Pipe-Roll of 31 Hen. I. in connection with Dorset. Dugdale and Mr. Eyton (_Addl. MSS._, 31,943, fol. 90) affiliate him as son of a Martin of Tours, who had established himself in Wales. He witnessed two other charters of the Empress (_Journ. B. A. A._, xxxi. 391, 395), both of them at Oxford. A son of his (filius Roberti filii Martini) held five knights' fees of Glastonbury Abbey in 1166.
[316] Robert fitz Hildebrand witnessed the Empress's second charter to Geoffrey with that to the Earl of Oxford (_vide post_). See for his adultery, treason, and shocking death (? 1143), _Gesta Stephani_, pp. 95, 96, where he is described as "virum plebeium quidem, sed militari virtute approbatum." He is also spoken of as "vir infimi generis, sed summæ semper malitiæ machinator" (_ibid._, p. 93). He is affiliated by the editors of Ordericus (Société de l'Histoire de France) as "Robert fils de Herbrand de Sauqueville" (iii. 45, iv. 420), where also we learn that he had refused to embark upon the White Ship. He was perhaps a brother of Richard fitz Hildebrand, who held five fees from the Abbot of Sherborne and five from the Bishop of Salisbury in 1166.
