Geronimo is a census-designated place (CDP) in Guadalupe County, Texas, United States. The population was 1,032 at the 2010 census. It is part of the San Antonio Metropolitan Statistical Area.
In 1831 during the Mexican Texas period, James Bowie surveyed eleven leagues of land within the colony ofGreen DeWitt. Located on the northeast bank of the Guadalupe River, the area surrounded the natural springs called Tio Geronimo. José Antonio Navarro purchased land and lived here later, 1840-1853. As a champion of human rights, he was a signer of the Texas Declaration Independence, the Constitution of the Republic of Texas, and the Constitution of the State of Texas.Navarro lived here on his 6,000-acre (24 km2) San Geronimo Ranch. It was located on Geronimo Creek and named for Saint Jerome (translator of the Bible into Latin). The town and creek are named to honor this saint,although others claim that the name comes from original owner of the springs, "Tio" (Uncle) Geronimo Flores. José Antonio Navarro's brother, Luciano Navarro, also ran a ranch in the area. The area is about seven miles (11 km) north of Seguin, Texas.In the mid-1800s, Geronimo became popular as a social center for German settlers. German settlers fromSchumansville moved into the area in 1860 and formed a settlement. One enterprising settler opened a bank and German civic center. The community had grown into a small town by 1891, sporting a general store, a post office (former bank), a steam-powered cotton-gin, and a population of twenty.
