The sometimes seen birth year of 1780 appears to be associated with the Joshua W Smith who died in 1831. The only death of a Joshua W Smith recorded in the Ellington Vital Records is in 1839. The 1831 references come from Barbour's collection of cemetery inscriptions and newspapers. No newspaper reference has been found. If these are the same man, perhaps there is a transcription error in one of the records.
