I'm wondering if your grandmother would know anything about Muriel and Robert's father. It must have been talked about in the family since Olive never married. Muriel would never talk about it so my husband doesn't know anything about his grandfather.
I'll give you access to my tree. It actually goes back to the 1200s which is amazing. Also, an ancestor was on the first boat of Walloons to come to this country in the 1600s.
