It doesn't look like Theotiste to me. The first letter of her name looks the same as the "A" in Albert and Ann.
I couldn't find any Norbert or Albert Mandevilles born in 1831 in the Drouin Collection, only much later. If he went by Norbert and was married as Albert then it is possible that he is also Gilbert.
