Jose Ygnacio Franco Coronel was born in Mexico City, joined the Spanish army and by 1814 rose to the rank of corporal of the cavalry. He married Maria Josefa Francisca Romero (1802 –1871), a native of Toluca. In 1834, as a part of the Híjar-Padrés Colony, Ygnacio brought his family (two sons, Antonio F. Coronel and Manuel F. Coronel, four daughters, and his nephew Agustin Olvera) to Alta California, where he started a new life as a civilian. Ygnacio Coronel was a schoolmaster. In 1836, Coronel was appointed commissioner of the securalized Mission San Miguel Arcángel. In 1837 he taught in Los Angeles, and afterwards he was secretary of the Ayuntamiento (Los Angeles City Council). In 1843 he was granted Rancho La Cañada.
