A valuable resource for determining whether a particular surname has already been linked to a Mayflower family is the Bowman Files. This is a data collection encompassing about 80,000 individuals, compiled by George Ernest Bowman (founder, secretary, and genealogist of the Massachusetts Society of Mayflower Descendants, founder and editor of Mayflower Descendant, and the first great Mayflower researcher) over the course of more than 40 years. Susan Roser has compiled a series of books extracting and transcribing information from the Bowman Files. The surname Belfry does not appear in any of them.
