I ran a death certificate on an Eliga Smith Roby, born Sept. 17, 1835. It listed his parents names as Thomas and Katharyn (Bash) Roby. Eliga was married to Elizabeth Jenkins and they are both buried in Ebeneezer Cem. in Morrow Co. OH. Eliga and Elizabeth had 6 kids, Estella, Charles F., John, Mathew, James, and Nancy J.
Hope this helps and if this is your Elijah Roby, please contact me at firstname.lastname@example.org
