A Little Bit about Tuolumne County

Tuolumne County was one of the original counties of California, created in 1850 at the time of statehood. Prior to statehood, it had been referred to as Oro County. Parts of the county were given to Stanislaus County in 1854 and to Alpine County in 1864. Tuolumne County tidbits:

Tuolumne County tidbits:

  • The name Tuolumne is Native American in origin and has been given different meanings, such as "Many Stone Houses", "The Land of Mountain Lions" and "Straight Up Steep" - the latter an interpretation by William Fuller, a native chief. Mariano Vallejo, in his report to the first California State Legislature, claimed that the word is "a corruption of the Miwok word talmalamne, which signifies 'cluster of stone wigwams'."

  • As of the year 2010, the total population of Tuolumne County was 55,365 (that's approximately 9 people per square mile).

  • The county seat is Sonora, also the only incorporated city within the county.

  • Tuolumne County's 1,030,812 acres (4,171.55 km2) include federal lands, such as Yosemite National Park, Stanislaus National Forest, Bureau of Land Management lands and Indian reservations.

In the spring of 1996, a group of genealogists with mutual interests in Kentucky genealogy organized the Kentucky Comprehensive Genealogy Database Project. The idea was to provide a single entry point for all counties within the State of Kentucky where collected databases could be stored. Furthermore, the databases would be indexed and cross-referenced, so that even if an individual was found in more than one county, he or she could be located in the central index. This idea spread quickly to other states and, by the end of the summer of 1996, the USGenWeb Project was born. This project is an outgrowth of that original project. Today, the USGenWeb Project is a loosely organized group of volunteers that work to create a center for genealogical research for every county within the United States. Visit the USGenWeb Project.

In June 1996, as the Kentucky Project was coming to together, project organizers decided to create a page for each state, establishing the USGenWeb Project. Project organizers located volunteers that were willing to coordinate the collection of county pages for every state. The first California USGenWeb Project page was loaded onto the Internet on 16 Jul 1996. If you would like to sponsor a California county, or volunteer in any way to help with the CAGenWeb Project, contact Martha A. Crosley-Graham, the California State Coordinator, at marthagra(AT) – substitute the (AT) for an @ symbol.
