Hi - I am the granddaughter of Frank Tapley VanDine. My mom remembers her grandmother Mary. Her aunt Alice is still alive and living near Shipman, where the family settled. I have the baptismal and marriage records showing the information you have. Even when they were young, my mother said they didn't acknowledge their First Nations heritage - hence, I believe, the story that they were French Canadians (a little like the Conehead family on SNL?) I am still searching for Mary and her family - I'm going to see if there are censuses of the Ahtahkakoop reserve - sometimes censuses were done by churches or other groups. I'll keep you posted. I have a picture of Mary and her family.
