Marguerite's parents were: Lambert Amable Robillard b. March 30, 1751 Madeleine Marie Boileau b. August 11, 1758
She had two brothers: Alexis and Jacques
Lambert's father was Lambert Robillard. His father was Nicolas Robillard and his father was Claude Robillard who came from France in 1663 at the age of 13 without his parents. I have a footnote that indicates Claude was from a small town of Riom which is a little way west of Lyon.
