Career
Beatrice was first betrothed not long after her birth on 4 March 1223 to Manfred III, Marquess of Saluzzo. However, the contract was broken off but was then renewed on 2 October 1227. A contract signed on that date refers to the dowry of Beatrice.
The couple were married in March 1233.
They had the following children:
Alice (c 1236 – before 12 July 1311), married Edmund de Lacy, Baron of Pontefract and had issue
Thomas (1239–1296), succeeded Manfred as Marquess
Agnes (1245 – after 4 August 1265), born posthumously, married John, son of Eustace de Vesci, no issue
Margaret (born 1245), born posthumously, twin of Agnes
Her marriage was arranged to recognize an alliance between Beatrice"s father and Frederick. In a testament from Beatrice"s father dated 24 May 1253, the succession rights of Beatrice were bypassed in favor of her younger half-brother.
The testament fails to mention Beatrice"s second husband, possibly indicating a breakdown in the marriage. Beatrice died before 1259.
