I found recently that Betty Smart, Jim Smart's wife's name was Elizabeth Jones Smart(nickname Betty) and Jim's name was Samuel James Smart. Jim was his nickname. Luther Smart was my grandfather and Mack Smart was his brother. Uncle Mack's family lives in California. I am trying to find evidence that Jim's dad was Samuel W. Smart born in La. around 1827. Some facts seem to fit. Samuel W. had a sister named Susan. Susan Smart married Buckner T. Smart in 1864. That's right, a Smart married a Smart. On Jim Smart's death certificate is listed Buck Smart, father. However there is no evidence that Buckner Smart had a son named Jim. Maybe some facts that you have might help.
