The Daughters of the American Revolution provides an ancestor search tool through its online Genealogical Research System to determine if a specific person served in the Revolutionary War. Alternatively, there is also a descendant search tool that cross-references the ancestor and member databases.
The spelling of a name is important when searching for an ancestor. Spellings often vary, and DAR.org suggests checking alternative spellings while using its tools.
The information contained in the database is not a complete listing of all Revolutionary War veterans. New names are added as the organization processes applications and verifies genealogical information. If the name of a supposed veteran is not included in the rolls, it is possibly because that person's participation in the war is not verified as of yet.
