I have a Smart/West connection in my Vernon Parish family, also. My Gr-grandmother, Lydia Crews West, was the daughter of Madison West and Nancy Henderson. Madison and Nancy also had a daughter named Nancy who married Dr. E.E. Smart. I believe that they started the Smart Chapel Cemetery near Leesville...might be a place for you to look. Madison's home was in the Silver Creek area closer to Walnut Hill and Slagle, though.
