Wow, you found alot of information I did not have.I must have gotten the wrong John Harold Bates when I was looking for him.I think the one you found in MA seems to be the correct John Harold Bates that I am looking for.
It's hard to confirm since my father, his sister and brother have passed.From what I've heard, Nina was married to a George Sangdahl (borned in Ohio), had two sons and divorced. She later married John Harold Bates.I think John Harold Bates was married before and the story I ehard was that John Harold Bates' ex went on to marry George Sangdahl.Not sure how true as I have not been able to confirm. I have not had a chance to meet the Sangdahl family, which are the only relatives on my grandmother's family that are alive.
On my father's side, I was able to trace them up to John Newlin and Elizabeth Cowinder but I have not been able to confirm that these people existed.I have not been able to find any Cowinder's so I am not sure if I have the right name.
I want to thank you for your help.The information you provided is great.Thank you.
