I looked through my notes and found a little information, I hope it is correct and helpful. Joseph Larocque and Philomene St. Denis had five kids. I don't know their birth order off-hand: Julia Larocque, Victoria Larocque, Alexander Larocque, Mary Josephine and Agnes. They have a lot of French ancestry. My mom remembered hearing that Mary Josephine married a man with the last name of Neely (not sure about spelling) who was a Highway Patrolman who was working out of Polson, Montana. They moved to Polson and didn't really stay in contact with her family.
I will call my Aunt and one of my cousins who know a little more about the family history and see if they have any other information. Good luck, hope that helps!
