My gr-grandfather Louis Armand was born in Bergerac, France on 18 Oct 1842. His parents were Joseph and Margaret Fonvielle Marc. He married Marie Therese (Charlotte)Marc and lived in NYC where their daughter Marie Blanche was born on 28 June 1883. It is not known whether they married in France or US or when they immigrated. If anyone has any information on this family I would appreciate hearing from you.
