Hey, Experts en Héraldique Français

The local château is flying a new flag, does anyone know what it is, or do I have to email the châtelaine? [Who is delightful, but I hate to bother.]

The closest match I can find for the heraldic charges is a woman whose family came to Aix-en-Provence in the 17th century as Secretary for the king, Angelique de Fagou. So happy pride, I guess.

[few days later update: utter silence. we may never know.]
