A family tree on FamilySearch.org shows that her huband Armistead Morris had 2 marriages. "Mary Ann Check" in 1855, and "Polly Ann Brown" in 1861. As Polly Ann Brown was married to a Cheek, it is possible the two wives are the same person, and thus Polly Ann Brown and Mary Ann Cheek/Check may need to be merged once that is proven.
