George C. Yount was an early settler in Napa County and is believed to be the first Anglo-Saxon resident in the county. In 1836 Yount obtained the Mexican grant Rancho Caymus where he built what is said to be the first log house in California. Soon afterward, he built a sawmill and grain mill, and was the first person to plant a vineyard in the county. Following Yount's death in 1865 at age 71, the town of Yountville was named in his honor.
