I have made a small step in this query. Mary Jane Hartless born 1848 in Amherst Va was the daughter of Benjamin Hartless (Hartty) and Sofrona Rowsey b 1816. I have seen a copy of the marriage record for Sofrona and Benjamin. They were married Jan 17, 1842. If something happened to Sofrona, there would still be time for him to marry Mary Burch in 1855. If know anything further on Sofrona or Benjamin, let me know. I am still searching for his parents.
