He was a Spanish soldier who served in Alta California, then stayed to settle in the two-year-old Pueblo de Los Angeles in 1783 with his wife Maria Ysabel Urquidez (1750–1801) and 6 children: Jose de Santa Ana Avila y Urquidez (1770–1806), Francisco Jose Avila (1772–1832), Agustina Avila (born 1775), Anastacio Avila (born 1776), Antonio Ignacio Avila (1781–1858), Ildefonsa Avila (born 1782).
After settling in Los Angeles, three Californio children were born: Bruno Ygnacio Avila (1788–1861), Maria Hilaria Avila (born 1789), and Jose Maria Avila (1790–1831). Cornelio Avila died while visiting Santa Barbara in 1800, and was buried at the Presidio Cemetery.

Maria Ignacia Marcia Avila (1793–1858) was a daughter of Jose de Santa Ana Avila y Urquidez and Maria Josefa Osuna y Alvarado. She married Jose Delores Sepulveda of Rancho de los Palos Verdes in 1813. After his death she married Jose Antonio Machado of Rancho La Ballona.
Francisco Avila (1772 - April 5, 1832) was a wealthy ranchero and alcalde (mayor) of the pueblo of Los Angeles 1810 - 1811.
Francisco Avila was a native of Sinaloa, Mexico. He was one of several sons of Cornelio Avila. Francisco came to Los Angeles sometime after 1794. In 1810, Francisco Avila became alcalde of the pueblo of Los Angeles. The pueblo's population at the time grew to 415 inhabitants.
In 1823, the Mexican government granted him 4,439 acres (17.96 km2) of land Rancho Las Cienegas, near La Brea Pits, approximately seven miles west of the pueblo. Avila grazed cattle here and turned it into a profitable venture. The Avila land grant was bordered on three sides by four other ranchos (Rancho La Brea, Rancho La Cienega o Paso de la Tijera, Rancho Rodeo de las Aguas and Rancho Rincon de los Bueyes), which in later years led to many boundary disputes involving Avila and the other owners. The Avila Adobe built in 1818 by Francisco Avila, still stands today in the heart of historic Olvera Street.
In November 1826, Avila was one of the local notables invited to Mission San Gabriel by Father José Bernardo Sánchez to meet explorer Jedediah Smith, the first ever to travel overland to California from the United States. 
Francisco Avila married Maria del Rosaria Verdugo (1793–1822) the daughter of Mariano Verdugo and Maria Gregoria Espinosa in 1810. Maria del Rosaria Avila died in 1822, and Francisco married Maria Encarnacion Sepulveda, the daughter of Francisco Sepulveda owner of Rancho San Vicente y Santa Monica. Francisco Avila died on April 5, 1832, and his four children (Januario Avila, Pedra Avila de Ramirez, Francisca Avila de Rimpau, and Louisa Avila de Garfias) were granted the patent to Rancho Las Cienegas in 1871.

Bruno Ygnacio Avila (1788–1861) was one of several sons of Cornelio Avila. Bruno Avila regained for his family Rancho Aguaje de la Centinela from Ygnacio Machado in 1845 through an exchange of property. Bruno Avila, owned a modest adobe town house near present-day 7th and Alameda Streets in the pueblo of Los Angeles. It was a three-room structure on a small tract of land with a fenced in vineyard. Machado traded his entire rancho, including the adobe hacienda, for Bruno Avila's pueblo property. Bruno Avila moved into the Centinela adobe and went into the business of raising cattle on the land, which was adjacent to his brother's Rancho Sausal Redondo. Within ten years, Bruno accumulated several thousand head of cattle. In 1854 he borrowed $400 from John G. Downey and agreed to pay six- percent interest per month, or seventy-two percent per year, which was the standard lending rate at the time for private loans. The following year he borrowed $1400 from Hillard P. Dorsey at a similar interest rate. Avila, who put up Rancho La Centinela for collateral, was unable to repay the loans and subsequently lost his rancho in 1857. The land was seized and auctioned off at a Sheriff's sale.

Jose Maria Avila (1790–1831) was one of several sons of Cornelio Avila. He was alcalde of Los Angeles in 1825. He was first married at Mission San Diego to Maria Andrea Ygnacia Yorba, daughter of Jose Antonio Yorba and Maria Josefa Grijalva who was the daughter of Juan Pablo Grijalva, a Spanish soldier who traveled to Alta California with the expedition led by Juan Bautista de Anza and was the original petitioner for the lands that became known as the Rancho Santiago de Santa Ana.
