There is a hereditary organization for descendants of Colonial tavern keepers. Their website has a table of contents of members’ brief bios. There may be valuable genealogical info there. It also explains the qualifications applicants need to the society. State archives may have old tavern-keeper applications. Besides running taverns they also performed civic duties and provided a place for local meetings. Don’t forget, The Boston Tea Party was planned in a tavern. The website is www.flagonandtrencher.org.
