I have no information for you but I am looking for the same thing. Your grandfather(great grandfather?) Donald Simpson was my grandmothers brother. My grandmother was Blanche, the youngest child. I am interested in finding out where that property came from also. My mother remembers Ollie coming to her home as a young child and he was requesting permission from all his children to sell the holding. It makes me wonder if the property came from Mae's family and not purchased within the marriage. If you find anything I would love to know. I saw the property about 1962 in a drive by with my Aunt, I really don't remember much about it except I was intrigued.
