Local Meet-ups
Members gather together in homes, public libraries, cafes and even community rooms in condominium units. A facilitator leads the discussion as members share research topics, common interests, new resources discovered in an informal setting. Friendships have developed along with partnerships in resources and a better understanding of the many benefits available to CGS members.

Special Event:
The Leeds Method Can Unlock DNA Mysteries
Presented by Stewart Blandón Traiman

Learn to use the Leeds Method to turn cousin matches into meaningful connections. Open to all levels of DNA experience.
The first challenge in DNA analysis is making sense of those thousands of cousin matches. How do you turn genetic chaos into meaningful connections? By using the Leeds Method—a simple yet powerful color-coding technique that helps you group your DNA matches into family groups. By organizing your matches into clusters, you’ll start identifying family lines, linking distant cousins to your tree, and even uncovering long-lost connections or hidden family mysteries. In this class, you’ll learn step-by-step how to apply the Leeds Method to your own results and turn your DNA data into real discoveries!
The event will take place via Zoom. If you join, please sign in early to make sure you are able to see the program. We will send you instructions the night before, and a reminder shortly before the event, which will give you access. Our remote classes now have live closed captioning. When registering, use an email address you will be checking. Please note all times are Pacific Daylight Time.
