I'm finding that there seem to be quite a few Blackard families in the Tn and Ms region who seem to be unrelated. The coincidence here is that Job Blackard is my 4th Great Grandfather. My Grandfather (Fred Galviston Blackard) had a brother named Robert Lee (b: 8/17/1885, d: 12/3/1967). Robert Lee married Irene Hickey (b: 3/22/1886, d: 5/15/1956). It looks like this is not who you are looking for; however I was surprised at the coincidence.
