Cesar Estrada Chavez was born in Yuma, Arizona on March 31, 1927. He was named for his paternal grandfather, Cesario Chavez, a Mexican who had crossed into Texas in 1898. Cesario had established a successful wood haulage business near Yuma and in 1906 bought a farm in the Sonora Desert's North Gila Valley. Cesario had brought his wife Dorotea and eight children with him from Mexico; the youngest, Librado, was Cesar's father. Librado married Juana Estrada Chavez in the early 1920s. Born in Ascensión, Chihuahua, she had crossed into the U. S. with her mother as a baby. They lived in Picacho, California before moving to Yuma, where Juana worked as a farm laborer and then an assistant to the chancellor of the University of Arizona. Librado and Juana's first child, Rita, was born in August 1925, with their first son, Cesar, following nearly two years later. In November 1925, Librado and Juana bought a series of buildings near to the family home which included a pool hall, store, and living quarters. They soon fell into debt and were forced to sell these assets, in April 1929 moving into the galera storeroom of Librado's parental home, then owned by the widowed Dorotea.
