A local genealogy gave Benjamin Butler a daughter named Frances Ann Butler. This was an error, there was no Frances Ann. The local genealogy saw a Francis Adams at Hillside Cemetery, New Gretna, NJ and assumed this was the wife of Mark Adams. This, in fact, was his brother Francis A. Adams.
In his 1893 will, Benjamin Butler made a bequest to his daughter "Willieanna", wife of Mark W. Adams.
