Hello, Yes I have information about John and Roena Callihan. Roena is John's second wife, his first wife was Isabella Bowen. Isabella and John were your Robert's parents. John is the son of Thomas Callihan Bedford County PA. Genforum has quite a bit of information about Thomas.
There is not a lot of verifiable information about John and Isabella Callihan's children. So far I can prove George Callihan, Robert B Callihan and John H Callihan. I recieved an e-mail recently form someone sho said they thought Elizabeth Pierce married to Joseph Pierce, was formally Elizabeth Callihan daughter to John Callihan. It is possible especially since Elizabeth lives next door to John and Roena in 1850 census PA Clarion County pg 207.
Anything you find to help us put together John and Isabella's children and their families would be appreciated.
I would love to have information about Thomas B Callihan's decendents.
