I can give you some information on the MacMillan tree after my grandparents I am not sure of where they fit, only by name and dates.
I can complete the earlier part of my tree in a couple of months, I would have to visit where my parents are buried.
I am looking for a cousin who I think is alive. I have searched his name over the internet and haven't had much luck. I really can't afford to pay to find out either..
