stewart andrew longstreet 1925-1990 canada

I am looking for any and all information on Stewart and his immediate family (siblings, parents etc.)Especially any information on his upbringing(where born etc.).I would like to know more about my dad, as I really did not know him that well, and he did not talk about his family at all.I am his daughter, and really do not know much about his side of the family.I know that he had a sister Daisy and a sister Kathleen. I believe that his fathers name was Frank Longstreet and his mother's name was Isabella Machan.Any and all help is much appreciated!!
