The Abraham Ott who was born on 13 February 1799 is the wrong Abraham.The one born on that date was the son of Abraham Ott Sr and Ann Green; he died in 1819, at age 20, leaving a widow (Mary E.) but no children.(Mary E. later married John W. Bruen.)His brother-in-law, John Wolfe, was named administrator of his estate.
Your Abraham Ott was born, according to the 1850 census, around 1801.According to Peggy Ann Easterling Miller ("Otts of Branchville, S.C."), his wife Margaret was a Rhoades, not a Connor, and they were married in 1824.I don't know what her evidence is for that.
For that matter, I don't know what the evidence is that Margaret was a Connor, either, other than the presence of an Ann Connor in this family's 1850 census household.Can anyone enlighten me on this?
