Hello again, I am looking through my files and I see a tree on Ancestry under Worrell, Olson History by Karen Goodwin She has a Johannes Dunckel 1703 Germany immigration 1730 to Phiadelphia Pa.
I have 1810 census showing Peter sr. in Toby, Armstrong Co. There is also a Mickal sr. in same census. 1830 I see a Jacob, William and a Henry.
The first census my Fitzgerald show-up in area: My Mathias and his son John live next door so to speak to Peter and Henry. 1840 everyone is still close together and the Kifer family and John henry Dunkle are in the neigborhood. There is a John Jacob Dunkle in the 1850, not sure if someone added a middle name to a previous Dunkle. It get more confusing from here. I know for sure that Dunkles moved on to Ohio.
