This place intrigues me. It is in the "Ridge and Valley Appalachains".."lying between Stone Mountain ridge to the north and Jacks Mountain ridge to the south"[1]. It is the current home of many Amish and Mennonite Families. My Sankey ancestors settled here around 1730 or 1750. It is a guess that they stayed in the valley about 50 years. North of Mifflin County is Centre County.
The Sankey family lived in Centre county from 1800 to 1860. My great grandfather was raised in Centre Hall with his cousin Laura Runkle.
