The creek, the town, and the county all take their name from the same man, Jose Maria Amador, Indian fighter, rancher, miner. On August 17 of 1835, Amador was granted an immense 16,517 acre tract of land known as the Rancho San Ramon, where he settled down and built one of the few two-story adobes in California. Amador began producing leather, soap, saddles, blankets, shoes, and wagons using Indians from mission San Jose, and was soon one of the wealthiest rancheros in the province.
