Longmont Genealogical Society
The Longmont Genealogical Society (LGS) was founded in 1986 for the purpose of promoting and assisting with genealogy research. Learning about your family history can be a most interesting and rewarding hobby.
Society members receive the Longmont Heritage, our quarterly newsletter containing articles on genealogy, family history and more. Members have the opportunity to join with others to help preserve community and genealogy information. Become a member of our Society and discover your talents and your family History.
