Quoted from K. S. B. Keats-Rohan, ‘Aubigné, William d' (d. in or after 1148)’, Oxford Dictionary of National Biography, Oxford University Press, 2004 accessed 25 May 2007
""Aubigné, William d' [William de Albini; known as William d'Aubigné Brito] (d. in or after 1148), baron, was a younger son of the Breton lord Main of St Aubin-d'Aubigné (Ille-et-Vilaine) and his Norman wife, Adelaide de Bohun. His name often appears as Aubigny and the cognomen ‘Brito’ distinguishes him from his Norman namesake, William d'Aubigny (d. 1139), the ‘Pincerna’, or butler, who came from St Martin-d'Aubigny (Manche). He assisted in the victory of Tinchebray in 1106, and became high in favour with Henry I, attesting numerous royal charters, the earliest belonging to the period 1104–16. By 1107 he had married Cecilia, elder daughter of Roger (I) Bigod and Alice de Tosny. He appears to have held lands in Lincolnshire, Leicestershire, Essex, Hertfordshire, and Northamptonshire, some or all of which were his wife's marriage portion. The bulk of the Tosny inheritance, however, including Belvoir, in Leicestershire, appears not to have been held by d'Aubigné and his wife until c.1130, after the death of Cecilia's mother, when Cecilia became principal coheir of her maternal grandfather Robert de Tosny (d. 1088), lord of the honour of Belvoir. Cecilia's younger sister Maud married William d'Aubigny Pincerna. In 1130 William Brito was an itinerant justice in Lincolnshire, and between 1135 and 1143 he attested a number of Lincolnshire charters by King Stephen. In 1146 Stephen granted William's estates to Ranulf (II) of Chester, but the general tenor of the grant, and the absence of any indication that William had joined Matilda, indicate that Stephen was disposing of the overlordship of William's estates in order to gain Ranulf's support, and not that he had suffered any royal disfavour. He lived at least until 1148, the earliest possible date for a charter he gave for Pipewell Abbey in Northamptonshire. "[3]
