Amanda,
I don't know if you received any information on your Great Grandparents, but I do know there is a Iddings Book with everything you would need. I believe Reuben and Bessie are my Father In-laws parents. His name is Junior Lee Iddings, I grew up with his nephew Ron Iddings. I know they lived in the Logan Ave area of Tyrone, near the Paper Mill. They had several children: Jim, Junior, Ron, and Ruby. There are several others but I don't know there first names. Hope this helps.
