Brothers Valley Township ~ 1768
(Note: This listing includes only those settlers known to have been residing in the vicinity of Turkey-Foot in 1768. They were forbidden by the Proprietaries of the Colony of Pennsylvania to reside on the lands not yet purchased from the Indians. This list was made by the commissioners sent to expel them from the region in March-April, 1768.)
Here are some people living in the area early.
