I found a record in Tallapoosa County, Alabama (Deeds F-619) in which a Thomas and Rebecca JOHNSTON assign a Jessie HAYNIE to represent their interests in the estate of a John MOMAN on 10 Jun 1851.
1850 Federal Census records and Tallapoosa County marriage records indicate that Jessie HAYNIE is their brother-in-law (wife's name is Jane) and that, probably, their mother is named Elizabeth JOHNSTON. All were born in Georgia.
Does anyone have any information about this John MOMAN? I would guess that he could be the father of this Elizabeth JOHNSTON, b.1805.
