My mother is a Donham also. My GGG grandparent are Lewis Donham and Amy Maple, GG grandparents are John Donham and Rebecca Engle, G grandparents are David Garrison Donham and Harriet Williams and my grandparents are William E Donham and Hazel Swart. I am trying to find information on Lewis Donham and John Donham. Unable to locate any information that they are father and son. If you could help I would greatly appreciate it.
