I am looking for any information regarding the parents of David Johnson, born in Ohio 1820. I believe his mother was born in Maryland and his father in Ireland. He and his wife Sophia De Bertrand spent their married lives in Belmont county, I'm assuming this is also the area where David grew up.
I am also looking for information on Sophia De Bertrand prior to immigrating to Ohio from the Guernsey Isle with her brother Thomas.
Any information would be appreciated.
