Simon was born before 1100. According to both Foster and William Sealy, he was the son of Humphrey de Cailly. The same view is held in earlier editions of Burke's Peerage (later editions do not go back this far in their Cayley pedigree).[1] He passed away after 1153.

He witnessed at least one deed executed by William de Warenne d. 1148.[2][3] In about 1153 he witnessed King Stephen's deed allowing William de Caisnei to enter into his inheritance.[4]

Research Notes

Keats-Rohan speculates that he may have been son of one of the Cailly family members called Osbern/Osbert, but makes clear that this is just speculation, and adduces no evidence to overturn the earlier view of his parentage. She agrees that he was father of Roger de Cailly.[5]
