Evelyn, Being in Bedford County you might be more aware of the county formation there. It looks to me like Roanoke Co. was formed from Bedford Co in 1838. It doesn't look like William Bush (1806) moved very far.???
Do you agree that Peter Bush is the son of James Bush who left his will in 1791 in Lancaster Co?
I trust you're keeping Charles in the loop about our conversations on this forum??
