Antonio died in 1841 without leaving a will. On his deathbed, he decided he wanted to reconcile with his son and, in a letter, offered Ygnacio several properties, including the Rancho San Francisco land grant he had received. Unfortunately, he died before the letter was delivered to Ygnacio, but the son returned to the family homestead to administer the ranch anyway. Without a will specifying how the estate was to be divided, Jacoba Feliz, Antonio's second wife who remarried after his death, filed a lawsuit to claim part of the land, which was the site the first recorded discovery of gold in California, sparking a minorgold rush in 1842, six years before the more famous California Gold Rush. Eventually, the lawsuit was decided and the land was split, with Ygnacio receiving the Rancho Camulos. However, del Valle did not live on this land initially, instead residing in the Olvera Street area of Los Angeles, where he was active in local politics. In the 1840s, he served on the junta as a member and its secretary, as well as treasurer of civil government under Governor Pío Pico. In 1850, he was elected alcalde of Los Angeles and served only a short time before the city was incorporated as an American city, but during his tenure he established the Los Angeles Rangers, an early law enforcement group. After California achieved statehood later that year, del Valle served in the California State Assembly for a short period. He was elected to a one-year term in the Los Angeles Common Council in 1852. and was elected again in May 1856 but resigned in December of that year.
Marriage
In 1852, at the age of 44, he married 15-year-old Ysabel Varela. Del Valle remained on the City Council for five years, after which he devoted his time to improving Rancho Camulos. The del Valle family, including five children, finally moved to the rancho in 1861. Ysabel del Valle was known to help poor and orphaned children and when then moved she brought eight orphans to live with her family.
Later life
However, the late 1850s and early 1860s were difficult for ranchers in Southern California. Severe flooding had caused great damage to many ranchos. Despite this, the Del Valle family, like many Californios, continued to live beyond its means. Del Valle had to pay off the debts of his stepmother, Jacoba Feliz, in return for which received part of her land inheritance. He had already sold off his Rancho Tejon to pay his own debts as well. The winter floods of 1861-62 were followed by droughts which lasted for three years, which forced del Valle to sell off his remaining land. He was left with just 1,500 acres of his Rancho Camulos, but the ranch survived these hard times and became a thriving operation, the source of the first commercially grown oranges in Ventura County. Through 1870, the del Valles had seven more children, although only five of the twelve would live to adulthood. One, Reginaldo, became the youngest-ever president of the California State Senate at age 28 and was instrumental in the preservation of Mission San Fernando, as well as the movement to have the El Camino Real marked with bells. Ygnacio del Valle died in 1880 and was buried on his rancho. Ysabel took over the running of rancho until 1900, then moved back to Los Angeles. In 1905, the ailing woman "refused to die" until she could be reunited with her long-dead husband. His remains were exhumed and moved to Los Angeles. Soon after their arrival, Ysabel died, and she was buried in the same coffin as Ygnacio. Their remains lie at Calvary Cemetery.
