 His younger brother, Louis de Rigaud de Vaudreuil, was also a Navy officer.They served together in 1747 on the 74-gun "Intrépide".Although his father was born in Quebec City and there are claims that Louis-Philippe the son was born in Canada, it is more probable that he was born in Rochefort, France, as his father was in charge of that city on the west coast of France at the time.
