[2] Her parents were Louise Mossbauer, a young servant and Raphael Benucci a coachman of Italian origin.

[2] She married Raymond Poincaré in a civil ceremony in Paris on 17 August 1904.

[2] The marriage was secretly solemnised religiously on 5 May 1913, a few months after Raymond was elected to the presidency of France, in their apartment at 10 Rue de Babylone (7th arrondissement of Paris) by the rector of the Catholic Institute of Paris, Mgr.

[8] Poincaré was a member of Aéroclub féminin la Stella, founded by Marie Surcouf.
