John Silas Ashworth Sr. is found in the 1880 Tazewell Co VA Census with wife Ellen and children Robert, Louretha, Elizabeth, Joel, Thomas, Amanda.John Silas (Jack is on his gravestone) is buried across the road from me, outside of Big Stone Gap, Wise Co VA. My husband descends from daughter Amanda Bessie who married Robert Jackson Treadway in Scott Co Va on Feb 24 1895 which is the date you have posted as when Jack married Laura Ellen Conley. I may be very mistaken but I thought Ellen Conley was the mother of Jack's children (no proof). John Silas's father Joel Ashworth, Jr. and mother Elizabeth Edwards are found in Carroll Co VA, they were married in Grayson Co VA in 1836. Elizabeth is a descendant of the Boone Family which included Daniel (they were 1st cousins twice removed). Have more information if you would like.
