The only refernce in a book to this William is Copinger's Suffolk Manors.  This is a very unsatisfactory account as Copinger gets several items wrong and slates another author for doint he same when it is more probable that the other author was correct.  Nevertheless the very strong lklihood is that this William is who Copinger says he is and accoringly he is so entered in this database.

Copinger thinks that William inherited Basilia de Limesi's half share in the Cavendish barony.  But he also relates that this William was given the other half share, Eleanor/Alice's, by Sir Henry Pinkeny who, it seems, dsp and surrendered his other, Weedon-Pinkeny, estates to the crown.  I wonder if Copinger mistook this second holding, from Eleanor/Alice,for the first, from Basilia, and got himself confused.

Anyhow if William got a share of the Limesi holdings this would account for his son being able to marry Ela filia Walter aka FitzRobert.  Otherwise William was a yonger son with few assets.
