|SOME NOTES ON MEDIEVAL ENGLISH GENEALOGY|

According to K.S.B. Keats-Rohan [Domesday Descendants, pp. 674, 675, 880 (2002)], Alice was the daughter and eventual coheir of William Meschin and Cecily de Rumilly, daughter and heir of Robert de Rumilly of Skipton.
[This question was discussed by Leo van de Pas, J.C.B. Sharp and Tim Powys-Lybbe in April 2002]
Volume 8, page 261:

Douglas Richardson, in October 2001, pointed out that a licence was given 1 July 1369 for their marriage at Bretby Castle; in the record, Margaret is described as the daughter of Sir John de Moubrey [citing William Salt Archaeological Society, new series, vol. 8, p. 47 (1905)].
[Margaret's identity was discussed in October 2001, and again in February and May 2002, by Douglas Richardson, Brad Verity and Dave Utzinger.]
