Hi. I believe I am also descended from Johannes Shroll. So far I have a Susan Shroll marrying Jacob Graybill. She was born in 1814 to Jacob Shroll and an unknown wife. He was born about 1780 in York County. Does this match with any of the info. you have. My e-mail is email@example.com
. Please e-mail me if you have any further info. to help me. We think Johannes would be Jacob's grandfather.
