You have a great Feg/Fake tree posted.
I do see the first one (below) and his large family that is on the in the 1717 THE SIMMENDINGER registere (Schoharie, NY) living in the village of Neu=Stuttgardt = (f)
Feck, Joh., (f) w. Anna Maria Margaretha & 5 ch
Feck, Leonhard, (f) w. Catharine
Feck, Peter, (f) w. Anna Maria & 4 ch
Have you discovered anything about his two children (probably) Leonhard and Peter? I did not see a wife for them or children if I am reading your tree correctly.
Finally, have you come across a possible daughter of Johannes named Anna Elisabetha Feg (m. a Walborn)?
Many thanks again for your great work. Cheers, Bert
