Companion of William the Conquerer (William I of England)
The following is extracted from "The Conqueror and His Companions" by J.R. Planche, Somerset Herald, London: Tinsley Bros. 1874

"Cil de Saie," mentioned by Wace (1.13,712) is supposed to be Picot de Say, one of a family deriving their name from Say, near Argentan, the lordsof which were vassals of Roger de Montgomeri in Normandy (France) as well as subsequently in England.

In 1060, Robert Picot de Say, Adeloyse his wife, their sons Robert* and Henri, and Omelin de Say and Avitia his wife, were benefactors to the Churchof St. Martin of Seez, and in Domesday we find Picot de Say registering holding under Earl Roger twenty-nine manors (enough room for all of ustoday!) in Shropshire. In 1083 he was amongst the barons invited by the Earl to witness his foundation of the Abbey of Shewsbury. He had probablyfollowed his feudal lord to England in 1067, and would not, therefore, in that case have been at Senlac; but, at the same time some of the familymight have been in the invading army, as Wace has represented Roger de Montgomeri as a leader in it, he would be likely to name one of his principalvassals as fighting in his company. Picot appears to have been the hereditary name of the family, it being sometimes used by itself, as in theinstance of Picot Vicecomes, or Picot of Cambridge, one of the founders of the Priory of Barnwell, or with a baptismal name prefixed to it, as inthat of Robert Picot of Say above mentioned."
