Quincy, about 1 1/2 miles east of here off Mule Creek, was one of the cities within Rancho Arroyo that suddenly appeared in the early 1850's. Don Andreas Pico bought the grant from Teodosio Yorba in 1844 with 500 head of longhorn cattle. Before its destruction, Quincy had grown quite large and, according to the Quincy Prospector, rivaled Sacramento in its best days. Settlers coming to California during and before the Gold Rush of 1849 built the town, and its people were shocked when Pico and his vaqueros rode in from Mission San Jose and told them to leave because they were trespassing. Pico was within his rights, and years of bloodshed followed in a loosely organized war of murder and ambush. The violence diminished with the arrival of infantry, field artillery, and cavalry from the Presidio of San Francisco, which garrisoned the area well after 1865, but this came too late for Pico's wife, who was murdered during this period and buried 6 miles south of Quincy near the Miwok town of Uoo-Poo-Soo-Ne. In the end, the settlers were given the choice of Ione or Quincy; Ione prevailed, and Quincy was evacuated, burned, and dynamited to the ground in two weeks. Despite the destruction, aerial photographs still show Quincy's four-lane main street with parking and many large side streets, visible in the short grass over the streets against the longer grasses inside the old foundations.
