In your June 4 correspondence you mentioned there is a problem identifying John Wieser(Nov 1758, Maxatawny, Berks, PA-ca Feb 1810, Greenwich,
Berks, PA) You listed Jacob Wisser as his son. According to your information Jacob Wisser would be my Ggggrandfather.
Since there is a spelling change there I am concerned about any ID problems. Can you elaborate more on the problem? Do you have any research leads that I could follow up on? I would love to take my tree back another generation or two but I want to be cautious.
