Through a recently acquired death certificate, I have found out that David Dougherty and Nancy Humphrey are my 3Great grandparents. They were both born in Ireland, supposedly Donegal, and were in Wheeling, Ohio, WV in 1847 when their son, Thomas Harris Dougherty was born on May 20. There were also two older sons and possibly other children. I am looking for any information on them...Does anyone have them in their family tree? Thanks for any help.
