John W. (Wesley?) VanLandingham

My great uncle, John W. (Wesley?) VanLandingham, joined the Confederate
forces approximately 1861 in Dale/Geneva County, Alabama, as a private 
He left his home, joining with other Alabama Units fighting battles during
the Civil War.  But when the war was over, he never returned to Alabama
and his family, who assumed he had been killed.  According to my
grandfather, his family never received any word from the Government---"he
just went away and never came back to us"---a statement that still haunts
living members of his family, needless to think what living a lifetime
without ever knowing what bacame of a son that gave his life fighting for
this country.In my search of Civil War Service Records online databases, I
have located only one record of a "John (J. W.) Landingham, 15th Alabama
Infantry Regiment, Company E, as a Private In and Out of Service; Film 
Source Number Box M 374; Extraction: 25; Record: 1539" having enlisted in
a Civil War Alabama Unit. The "Van"suffix is missing from the record.
Having lived for years with the surname of "Van Landingham", it was most
common in our locality to dispense with the "Van" preceding the
"Landingham" part.My question is:  Is there any search/contact that can
be made at this point in time to ascertain if this could be my great
uncle?  He was single, thus, no widow's pension, etc.  Would there be a
record of the parents' identity for this "J. W. Landingham", who were
Peter Van Landingham, Jr., and Sarah Ann Rawls Van Landingham? I would
appreciate so much any assistance you might be able to give me in the
hopes of resolving what might have become of this uncle.
