Yes, this is the LaGroux Family that is in our Ancestry.
Roseline Lagroux married Louie Laporte.
Roseline was the daughter of Casimir Lagroux and Anatome (Maiden Name Unknown???)
Roseline had a sister named Seline (possibly a disabled twin) and Roseline also had a brother, Gilbert.
After Louie's death, Roseline may have remarried a Mathieu? In any case, she had a son named Casimir Mathieu, who was half brother to her son, Leopold La Porte, our Ancestor. Do you have anymore information on the LaGroux family?
