Richardson's concern with Agnes apparently comes from Farrer's observation that in one charter Walter de Gand calls William the constable his nepos instead of brother in law. See SGM discussion of 2005, and the charter. Another charter reproduced by Ormerod apparently indicates Agnes used the Gand surname herself which might hint that it came from her father. Keats-Rohan also seems to distinguishAgnes in her entry for Agnes cites RRAN III, no.119 which shows both William the constable and William son of Nigel (same person?) making concessions with the family. It also cites Round's article onthe Leicestershire Survey, which is reproduced in "Feudal England". (Possible sighting of a William fitz Nigel noted in final footnote, and Agnes de Gaunt in appears in Botlesford Hundred.)
