My name is Tracy Tucker and I am from Brinston Corners (now just called Brinston). I was very excited to see your post as my great-great grandparents are Thomas and Catharine Brinston from Ireland (Northern Ireland - Fermanagh). Although we know that Thomas and Catharine were from Ireland they were originally from England.
I asked my mom if she knew of a Harold Brinston. She only said that he moved out west and that my grandfather went to visit him once (my grandfather was Thomas Lloyd Brinston and he was married to Fae Brinston). As for Albert being adopted my mother said that she did not believe that was true as we have never heard of any adoptions in the family (Brinston is a very small community and we have a very small family).
I have always assumed that the Brinston's arrived on the east coast first before travelling to Ontario however I don't know if that is true?
My mom would love to speak with you as she has more information than me. She was contacted by someone named Holly V. (sorry I have forgotten her last name) a few years ago - could this be a relative of yours?
