A tree on familysearch.org [a bit off on the ch] states the STEPHENS family was in 1830 Dale Co AL [Wm STEPHENS m Rebecca BROXTON] 1830 Dale Co AL, Wm STEPHENS had 3 sons/3daus [he probably d shortly aft this census].Living 2 doors away is Wm STAPLETON, same age group as Wm STEPHENS.Possibly Wm ST was Margaret's gpa. 1840 Dale Co AL, Rebecca STEPHENS...a couple of doors away is James & Nathan SPEARS. 1840 Dale Co: STAPLETON...Frederick, John, Job, Seaborn...all living very close to each other.
I believe Lydia STEPHENS, Eliz. SPEARS, Margaret STAPLETON are all gch of Rebecca. STEPHENS dau m a SPEARS son STEPHENS dau m a STAPLETON son Lydia belongs to a son of Rebecca/Wm.
I didn't find any marriages for Dale Co in the needed timeframe.
