Since you said you were interested in future findings......
I just received an obit from the Lynchburg News in Lynchburg VA stating that Robert H. Durphy was the son of Edward M.W. Durphey who lived in Charlotte, Prince Edward and Appomattox Cos VA.I have the entire tree on this man thru 30 years of work. I can now conclusively connect the MO Durphy line to the Lynchburg Durphey line.
This being so.......then Robert H. Durphy was born in Appomattox Co VA abt. Dec 1832.In 1850 Dinwiddie Co VA census he is listed as Dorphey.In 1860 St. Louis Co MO he is listed as Dorphy.
Robert was associated with the RR for years.I have a feeling that he met his wife because of his travels on the RR from Petersburg VA to MO.Their marriage was noted in a Petersburg VA newspaper in 1858.
