The town of Yolo was originally called Cochran's Crossing after its founder Thomas Cochran. Cochran settled there most likely in 1849, building a hotel. This hotel drew the Yolo Post Office on February 3, 1853. Cochran sold his 160 acres (65 ha) in 1855 to William Hammock, who was residing on the property, and who at one point would run the area hotel. Hammock sold part of this newly obtained land to his business partner, James A. Hutton, in February 1856. Hutton was later appointed as the postmaster, as well as elected County Judge. The town was known as Hutton's in the 1855 General Election when only eight men voted.
Hutton's was appointed as the County Seat on June 1, 1857 by the State Legislature, with the condition that the name of the town be changed to Cacheville. The name Cacheville probably came from the nearby flowing Cache Creek stream. A town plat was recorded on October 10, 1857, and the County Seat title equated to expansion in the town. It was at this stage in 1857 when Yolo County's first weekly newspaper, the Yolo Democrat, was published.
