Elwood, I have hopes you are still checking this forum.
I have nothing on the parents of Jincy Adams of Warren Co., GA but I do have her marriage and children.
She married Moses Smith b.2 Sep 1815 who married Jane on 17 Nov 1840 and d. 23 Apr 1893.The info I have has Jane born 24 Sep 1821, not 1816 and died 18 Apr 1897. Both are buried in the family plot on the Moses Smith farm along with his mother and probably his father and others.
Moses and Jane had several children including my g-g-grandmother, Cassandra Sophronia (sp?) Smith b. 18 May 1851.She married James Davis Waddell on 1 Oct 1868.
I have all of the Smith children taken from the Smith Family bible.I also have photos of James and Cassandra.
I also recently found a reference to a Jincy Adams of Warren Co who is on the list of American Indian descendants.No further details were found however.
I will be glad to exchange more details with you.
I need info on Jane's parents.Hopefully by the date of this posting you will have been successful in doucmenting them.I have been to Warren County and have researched the Adams but so far have not been able to determine her parents.
