Cathy, I have Jonas Congers, b. Abt 1793 Pendleton Dist., Anderson, SC d. 29 Nov 1836, Gwinnett Co., GA, m. Parthenia Pelfrey, b. Abt 1780.
The reasoning I have that these many be the correct parents is that Robert named one of his daughters Frances Parthenia (a very unusual name). She married Sanford McAlpin Martin. This is where our trees connect.
If these are the names that you have as the parents of Robert Eli Conger, I for one would like to know more about this line. Could you please share what you have with the Community?
