CCGSFirst Families of Colorado Recognition Program


Welcome to the Colorado Genealogical Society, the largest genealogical society in Colorado. We invite members and visitors who want to share our interest in family history and genealogical research to our meetings, classes, and special events. Most of our members are researching family lines outside the state of Colorado, but we share a common interest in family history and research skills. We treasure those wonderful discoveries about elusive ancestors and cheer each other in the search for more information. Visitors are always welcome at meetings, classes, and activities of the Colorado Genealogical Society. We hope you will join us.
