In Oct 2020, Gay Brennan established that the Wyndhams are not ancestors of the Newmans as used to be thought. See note on Dinah Wyndam's page.

Ealier notes from Jerry Gandolfo:

Thomas Mowbray, Duke of Norfolk: Acceded: September 29, 1397. Lord Segrave, Earl of Nottingham, Lord Mowbray 6th.
The two daughters eventually became the two co-heirs of the Dukedom of Norfolk. The Complete Peerage conflicts with itself on which was the elder daughter. Under Ferrers Vol.V, p357 it says that Isabel was the eldest, but under Norfolk Vol. IX, page.610 note c it says that Margaret was probably older as her son inherited the title.
