Sid, I see them connected at various online sites but nowhere do I see anything that documents them as father and son. No legal docs, census records, or church records. I see Elijah frequently with a death in 1850 however he seems to appear in the 1855 Alabama census in Tallapoosa County. I see Elijah with a dozen to fifteen children depending on the site and from a quick study, it appears only two of them may actually be documented (via Census record). I would see if you can locate probate records which if not online can perhaps be gotten through a local historical society or county records office.
