Children are all alive and live in Ontario. Three of the four are now grandparents. I am her son (No children). My mother's mom (Jean) died in 1968 Her dad (Alex)died in 1973. I am still in touch with her family so, if you get a chance to read this post and you want to write, feel free to email me at rwrstewartprimus .ca (no space) I would enjoy sharing what little I know.
Sorry I do visit the headstones of my mother and grandparents but for the life of me I can't tell you what is written on them.
