I have a William Morgan Harter who according to 1880 West Virginia Harrison County Census was born somewhere in Penna. in 1830 to a father that was also shown as being born in Germany! That is all I have. What are chances of finding a birth record some where in Penna for William or any reference to his particular Harter line???
I am pretty sure William is not connected to the TK Harter line nor the George Andreas Harter line. He is also NOT in Mary Harter's book.
