My mom corresponded with Denyse. I have some photos of her with her mother. But I cannot find any Baptismal record—born in 1932. I believe she passed away in 1997. She was buried in St-Hyacinthe, but the funeral was in Vimont in/near Laval on July 26, 1997. Her mother’s name was likely either Cyr or Chicoine. Perhaps she was adopted?

She was baptised March 14th 1932 in Saint-Hyacinthe, daughter of Henri and of Annette Cyr.
