Classes and Events
The California Genealogical Society (CGS) is more than just a research library. Come learn how to do genealogical research by taking classes. Learn about upcoming field trips, research trips, special events, and headline speakers.

Online Resources
Providing additional Online Resources on our website is a priority. These resources include lineage charts developed by our members, which provide finding aids and images. Search to find out if someone you are researching is included.

Special Interest Groups (SIG)
The society has special interest groups for members to link up with others doing similar research.
