Hello Bob. Thank You for getting back to me. I'm a descendant of William Callihan; so I know his part of the tree. I know his brothers and sisters names and parents names, but nothing more so if you could help fill in there or give me ideas where to look for that info that would be a great. The info I have I got from a World Family Tree (I don't remember the #) and I was hoping to work off that tree and try to add to it. So if you can help please send me the info and if there's info I might have that you want let me know and i'll send it. William Callihan is my ggg grandfather.
