According to a book written in 1988 by Micheal Fullwood, Esq., there was an Andrew born in Onslow County, NC in 1777 to a Thomas Fullwood and Louanna Wilkins. He had 3 brothers - Wilkins, James, and Thomas. He had 4 sisters, Ester, Catherine, Anna, and Mary (Polly). He married Abegail Campbell, and had David and Rachel that were raised by their gaurdian Abel Chester after parents death. He died in 1822 in Irwin County Georgia.
Hope this is the right one. No mention of him being adopted is made in the book.
