Is there documentation for the wife Jane Peverell?
Asking because Wikipedia only mentions one marriage and wife for this William Russell:
Marriage to Katherine de Aula
In about 1280 [1] William married Katherine de Aula, heiress of the de Aula family of the Isle of Wight, who brought to the Russell family the manor of Yaverland, Isle of Wight.
There's no mention of Jane Peverell as his wife on Wikipedia or in his profile notes here on Geni.
Thanks for any clarification, as I'd like to be sure who the mother of his son Theobald was.
