Notes for William (Robert) FERRERS 3rd Earl of Derby
There is substantial confusion over his name. See The Complete Peerage V4.p193
for an account. Personally, I feel there could have been two brothers,
William and Robert. Robert being the Earl and when he died at Acre his
nephew William son of his brother William suceeded, but no documents
support this theory either! In The Complete Peerage vol.XIV,p.250 it is
suggested that Robert is a fabrication by Vincent.
Earl of Ferrieres.
