Would like to get in touch with the decendents of James McCarrel and Annie Noah. They lived in Washington County, PA.

Do you mean Peter Noah who married Jane McCarrel they are from Wash Co. Penn the anna noah I have is the daughter of George and Ann C. ...I am working on my family tree for my grandfather Kenneth L. Noah (son of robert K. Noah ) so if you see this I think we might have a link lol

Peter would have been James' great grandfather. Same family, different branch.
If you google Conrad Phillip Noah, you'll find a wealth of information for your grandfather.

i share peter and jane (mccarrel) noah with you. their descendant was my grandmother's father
