Who are your grandparents? My great-grandfather was Jackson Adams (b. August 17, 1887) and he was the son of John Griffiths Adams and Sara Elizabeth McDiarmid. I have their other children listed as: Grace, Harry, Minnie, Alta, Fred and Mary. One of those would be your grandparent, right? I am interested in finding out about you and your family. We just found my uncle and his children because of messages like this one.
