Mlle Dagueville at the Eden Concert

When I read these bills from L'Écho des jeunes (April-May 1893) I first thought of the Eden Concert on the Boulevard de Sébastopol, Paris. Mlle Dagueville, though, was appearing at the Eden Concert in Angoulême. This is a pretty little city between Limoges and Cognac - it is also an area where I've found references to d'Aguevilles in the odd bins of the archives. I think it might be useful to try and discover whom this woman was.
