Doctor Newton Poss was born in GA on 9 Sep 1826. He married Jane J. Stephens in Elbert County GA in 1846. Jane was born 5 May 1830 (daughter of Henry W. Stephens and Sarah Faulkner).
DN Poss and Jane had 7 children: Albert (b: 1852 in GA); John (b: 1855 in GA); William (b: 1857 in GA); James T. (b: 1864 in AR); Mary Etta (b: 1867 in AR); Luther (b: 1870 in AR); and Doctor Newton (Newt) (b: 1874 in AR).
I do not know the ancestry of DN Poss. There is a lot of information about his wife Jane, though, as she is a descendent of the Joshua Stephens 1700 line of Henrico Co., VA.
I am descended from DN and Jane's daughter Mary Etta Poss. The area of AR that this family settled was Grant and Jefferson Counties.
