Mathilda d'Aubigny or not?

Stirnet's "Plantagenet4" page reports that William was married twice, and that Mathilde (Maud) d' Aubigny (d. 06 Feb 1216, daughter of an Earl of Arundel) was his first wife. That marriage appears to have not yielded any issue.

William's second wife, by whom he did have issue, was Maud Marshal (daughter of William Mareschal/Marshal, 1st Earl of Pembroke).
