My records indicates that the wife of Hugh E. Poston is Ann Nancy Lawson. Sarah Amanda was their last child as Hugh died in 1846. After the death of Hugh, Ann Nancy re-married to William Ard. I don't know the facts behind what happened then but in the 1850 Census, Ann Nancy and Sarah Amanda were residing in William Ard's home as being married within the year. Ann Nancy's other children remained in the home which was next door to William Ard.I am sure that the oldest son inherited the farm as that was customary at that time. The only proof I have is the census recorded her as the daughter of Ann Nancy. You can get your documentary from the 1850 Federal Census for Marion County on page 48. It took me a little while to figure all of that out.I hope this helps.
