Maud De Wymondham (de Bigod) - Maud de Bigod married to d’Aubigny

I can't find anything on Maud having married de Wymondham either. In fact, accroding to the dates on these connections, she's showing as having been born only 2 years AFTER her supposed son Richard de Wymondham b. 1801.

Unless this connection can be documented / proven, I think Maud de Bigod should be disconnected from the de Wymondham lines.

I think this may be where the confusion comes from:
"Sometime between 1121 and 1135, William d'Albini made a further grant to the Priory of Wymondham on the occasion of the funeral of his wife, Maud, daughter of Roger le Bigod. Ailwardus and his three sons again were witnesses (Ibid - Vol. 5 - Page 203; History of Norfolk - Blomefield - Vol. 8 - Page 115)."

So no, Maud Bigod wasn't married to de Wymondham, but the family were witnesses to a grant made in her namea by her actual husband.

(Much more interesting info at that link, including a snide takedown by J. Horace Round, who is always fun to read even when - as occasionally happens - he is a little off base.

Thanks for that info, Maven.
