Interesting family stories. My family on my father’s side was ethnic German going back in the Philadelphia area to maybe 30 years before the Revolution. No stories that I’ve heard regarding the period. The Germans in the area were somewhat divided in their loyalties as were just about every other group.
I’ve heard it estimated that 1/3rd were pro-revolution, 1/3rd were pro-Brit, and 1/3rd just wanted to be left alone. Some things never change.
Have you ever checked out the history of the Bradford Accords...It is my understanding the Rebel German farmers were very much involved in early statement to Governor Bradford. Your family may have signed it also.
We are told that the grandfather that spent the winter at Valley Forge left his home with crops in the field and his wife with a brand new baby....Other grandfather travel back and forth to Fort Pitt to serve.
