Note: Several sources state that William II fitz Neel, son of William I fitz Neel, died without issue. However the existence of Leucha fitz Neel seems to be fairly new, being a correction to both Ancestral Roots and Magna Charta Sureties. AR indicates Leucha was, perhaps a daughter of William fitz Neel, while she doesn't fit into any of the inheritance schemes for William. She certainly fits date-wise as daughter of William II fitz Neel. Perhaps she was illegitimate. She could also be a very late daughter of William I fitz Neel.
