I only met Aunt Marg's brother (a Mark) from Markham Ontario and his children and the daughter was about my age. I remember that we all went to the CNE (Toronto Exhibition) together.
I was not at Marg's 100 birthday party as we haven't really spoken in many years. I have lots of info on Grant's side.
We have a beautiful old property just east of Port Perry and just south of Lindsay. Kawartha's are beautiful.
I'd be happy to keep in touch.
