I do not think it is likely that Nancy Ann Young married John Henry Higgins, Sr.

Nancy BROWN, nee YOUNG, was born Aug 19, 1775 in Newberry Co., SC. She was the daughter of James YOUNG and Mary THOMPSON of County Down, Ireland. About 1795 she married Robert BROWN (b. abt 1762, Scotland). They had at least one child, Mary (b. Jan 22, 1798, m. Robert RUSSELL 1819, SC, d. Aug 2, 1851, Smyrna, Coweta Co., GA).
John Henry Higgins, Sr. might have been married to someone named Nancy Ann, but I do not believe it was Nancy Ann Young Brown. I do not manage this profile, but it is incorrect and needs to be detached or edited. You cannot believe everything you find on some other platforms.
