I am interested in the Abernathy's who married into the Clayton family in probably the late 1760's or 1770's probably in Brunswick county, Virginia. Elizabeth Clayton born 1748 in Virginia married William Abernathy and they later moved to Pulaski, Giles county, Tennessee.Also her sister Susan Clayton married John Abernathy. Since you have a John Clayton Abernathy as a son of Berry Abernathy I thought there might be some connection. Please let me know if any of this fits with what you have. Thanks, Randy.
