Amador City was originally settled in 1849 at what is now Turner Road and Amador Creek (an old wagon road between Drytown and Sutter Creek) by several groups of gold panners who were drawn to the area. One of these was the Sunol Group, which included José María Amador. He panned the creek, but his primary success was in providing supplies that he brought from his rancheria in the San Ramon area. The creek, city and county eventually carried the name "Amador", the city taking its name from the county.
