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.

CGS Members: Projects w/A Life of their Own
Years ago, Cindy Thomson began researching her ancestors who immigrated to Hawaii from Korea in 1904 to work on sugar plantations. After expanding her research to include Japanese, Chinese, German and Portuguese aunties and uncles who married into her family and also had plantation ancestors, she was riveted by the similar and different ways that they experienced Hawaii. To better understand these experiences, she started (and couldn’t stop) reading about Hawaiian history, plantation management, labor unrest, immigration law, and the 16 different racial and ethnic groups who worked on the plantations. This is a story of how historical and cultural context – including interactions between as well as within different immigrant groups – can enrich family history and connect your ancestors to a world beyond family.
