M..Gibson...(don't know your real name!)
I do not know of any sister of Harold. I am totally into the challenge to do research for her. What was her married name...if she had one?!
I have pictures of Harold, but don't think I have any of his family. I could send what I have.
Where do you live?
I live in Metro Detroit. You can send me e-mail directly to me @ firstname.lastname@example.org
I would like to see what pictures you have.
I will go digging when I get home from work later!
