It seems many came to Loudoun from PA. My Brady family came from York County, PA down to Loudoun County, VA when their son Benjamin Brady was 4 years old in 1765. He was born in 1761 in York County, PA. I am looking to tie him so other Brady's in the area, as his is the only name I know. Maybe someone knows the parents or of even another family that settled from York County around the same time.
