Emma de Montgommery, Abbess of Almenchêches

daughter of Roger II de Montgommery and Mable d'Alencon

Charles Cawley in MedLands does not show any primary sources supporting a marriage for her.

EMMA de Montgommery (-4 Mar 1113). Guillaume de Jumièges names (in order) "Robert et Hugues, Roger le Poitevin, Philippe et Arnoul, et les filles Emma, Mathilde, Mabille et Sibylle" as the five sons and four daughters of "Roger de Montgomeri" and his wife Mabile[499]. She is named and her parentage given by Orderic Vitalis, who lists her first among her father's daughters by his first marriage, and specifies that she was nun and abbess of Almenèches[500]. After the abbey was burnt in [1102], she fled to Saint-Evroul, returning the following year and dying about ten years later[501].
