Have you looked in Loudoun County, Virginia?My husband's Pash ancestor was Milly Pash who married Samuel N. F. Oliver in that county on 6 Feb 1798.
It appears Milly had a brother named John and that their father was John Pash Sr. I have never found their mother's name.My Pash files are in storage for a few years, but I vaguely recall the name Penelope in connection to John Jr. and that he migrated to Nelson County, Kentucky.
Milly and Samuel left Virginia, probably before 1805, and moved to Harrison County, Kentucky.By 1830 they moved from Kentucky to Vermilion County, Illinois where they lived the rest of their lives. Best wishes with your reseach.
