Not the wife of Robert, 4th Baron Willoughby, or mother of William Willoughby, 5th Lord Willoughby
Cokayne's Complete Peerage states that Alice, said to be daughter of William Skipwith, was the first wife of Robert de Willoughby and mother of his son William.[1] No sourcing is given, and subsequent research suggests that this relationship is wrong. See discussion in Douglas Richardson's Magna Carta Ancestry and Royal Ancestry.

Did Alice Skipwith exist? I have found no evidence that such a woman existed. If she did exist, she can't have been the mother of Robert\Willoughby's son and heir, William, otherwise the later intermarriage between the Skipwith and Willoughby families would have been disallowed as I have noted above.
Reviewing the evidence, I find every single piece of evidence pointing to the fact that Margery la Zouche was the mother of William Willoughby. This is based on chronology, heraldic evidence, onomastics, and the later Skipwith-Willoughby intermarriage. The traditional view that Alice Skipwith was the mother of William Willoughby appears to be erroneous.
