|SOME NOTES ON MEDIEVAL ENGLISH GENEALOGY|
Volume 7, page 530, note e:
Besides their son Robert, Amice and Robert [Earl of Leicester (d. 1168)] had three daughters: ... (iii) Margaret (see Round, Cal. Docs., no. 1062), m., after 1155, Ralph de Tosny (Robert de Torigni, vol. i, p. 339).
Margaret's marriage may have taken place earlier (see Tony, volume 12, part 1, page 765).
Volume 7, page 532:
He [Robert, Earl of Leicester (d. 1190)] m., before 1155-1159,(e) Pernel (Petronilla), heiress of the Norman honour of Grandmesnil ...
She witnessed a charter of Robert, 2nd Earl of Leicester, to the Abbey of Fontevrault, circa 1155-1159, as Petronilla uxore Roberti filii mei (Round, Cal. Docs., no. 1062).
Ray Phair, in July 2002, pointed out that David Crouch has suggested a revised date of 1160-1163 for this charter [citing The Beaumont twins, p. 204 (1986)], and that it may in fact date from 1162 or 1163 (see Tony, volume 12, part 1, page 765).
