The claim has been made that William Peverel was a bastard son of William the Conqueror. Th e source for this is an old pedigree in which Peverel appears to have been added to the famil y of William. There is no other documentation which presents a relationship supporting Peve rel's placement as a royal bastard (there are a few grants from the king, but there is no ind ication that these represent anything special). In addition, William had no other documente d bastards, which suggests that if he did have any, he didn't bother keeping track of them . The more recent authors that I have seen have tended not to favor such a relationship as b eing accurate.
