I have been off of my research for several months now but in looking also for Cynthia Ann Smith/Golightly and her mother I found just yesterday that Enoch H Fleece purchased 78.73 acres in what is listed as the Chillcothe land office on June 23, 1826 which it lists it as sale/cash. So if he and Nancy Smith were married, and I have found those same records of their marriage also, then they were still in Ohio as of the June 23rd, 1826 land sale date. I have just today looked up all of the Smith marriages in Ohio from 1789-1850 and recorded all of those Smith men who married a Nancy.However none of them were married in Lawrence County, Ohio. There are 24 possibilities however some of them can be thrown out as I suspect that they were married not to long before Cynthia Ann was born abt. 1822 or so. I understand your thinking that perhaps your Mary Ann SMith was related somehow to Cynthia.
