Where we Are ~

map of california and tuolumne county

Our county, pronounced “too AH loo me,” is located on the Eastern side of the Great San Joaquin Valley, in the foothills of the Sierra Nevada mountains. We are about an hour from Yosemite, which straddles our county and the one next to ours. We are located in Sonora, the county seat.


What we are ~

Mission Statement: The mission of the Tuolumne County (CA) Genealogical Society is to foster, encourage, and promote an interest in genealogy by providing information, education, and inspiration to our Society members and the general public.

Who we are ~

We are a society incorporated as a 501(c)(3) organization, thus qualifying for tax deductible donations. We operate within the structure of a corporation with a Board of Directors and Officers. We have approximately 150 members, many of whom work tirelessly in our library. It is a space shared with the Tuolumne County Historical Society on alternating days. For further information, please see the "About Us" link.

This site is undergoing revision with new sections and new pages. Please excuse the "links to nowhere" while this change is being made. Your "Home" link should work on all the pages; of course, you can also use your "back" button on your browser. I apologize for this inconvenience and hope to have all the new pages and links working within the next week. Meanwhile, I hope you will continue to check in and see what's new. Any questions, please feel free to email them to the office. Thank you!
