I am from Gilles Chauvin and his 1st wife's line. She was Madeleine Cabassier. It is their daughter Marie Louisa Daniele who married Nicolas Perthuis. I also have many ancestors in the Indiana area, esp Post Vincennes. madeleine probably died of childbirth complications, as she died about the time daughte was born. Gilles married Angelique the next year. I don't have a death date for Angelique either.
some Cabassiers went to Indiana also. What state are you from?
