However, on Marcia's side, I was able to go much further back. Her grandparents were Roy and Sydney Jones. That is where the Joneses end. Sydney Keller Jones's line continues back seven more generations to Georg Keller, 1670-1750, in Germany on her father's side. Marcia's great-great grandmother was Eva Kern, David Keller's wife (1775-1850). Her parents were George Kern and Juditha Kern. Juditha Kern's father's line goes back six more generations to Steffan Kern, 1542-1583. Katharina Hanssen's (Steffan's wife's), father was Lorentz Hanssen, 1525. On her grandmother Bessy Newton Lowe's side, it goes back eleven generations to John Newton, 1572-1633, in England.
So far I have identified 184 people in the Roe/Jones family trees.
This is a picture of the Roe side. The Jones side is much bigger. It won't fit on one screen.
