Henry Dalton was born in London on October 8, 1804. On July 7, 1819, at age 14, he was apprenticed to Winnall Thomas Dalton as merchant tailor for a period of seven years. In 1827 he was in Peru, where he purchased for $3000.00 certain articles in corner Public House in Callao, apparently for commercial purposes. He engaged in coastal trade and commerce in Peru and Mexico, extending his interests in Mexico when he contracted for the purchase of the estate of the Marques de San Miguel de Aguayo. Through 1842 Dalton's business correspondence, although including Peruvian interests, was written from cities on the Pacific coast of Mexico, while his coastal trade was extended northward to San Diego, San Pedro and Los Angeles. He acquired property in both San Pedro and Los Angeles as early as 1843, from which time he appears to have been definitely established in California. In 1844 he purchased Rancho Azusa from its original grantee Luis Arenas; thereafter interested himself more in ranching than in shipping, although he maintained his commercial establishment in Los Angeles as an outlet for the surplus production of his various ranches. After 1846, when he charted a cargo vessel between Callao, Peru and California, he seems to have diminished his trading relations with Peru, but he never abandoned his Mexican contacts.
Acquisition of land in California progressed rapidly after the Azusa purchase. In 1845 Pio Pico granted two extensions to Rancho Azusa, one of which had been part of the San Gabriel Mission lands. Henry Dalton gradually accumulated properties until he became the owner of five ranches: Azusa, San Francisquito, San Jose and Addition, and Santa Anita. Other miscellaneous properties were acquired in and near Los Angeles. Santa Anita was sold in 1854; Francisquito was disposed of in small tracts between 1867 and 1875. Azusa was lost to the squatters through a series of highly questionable court decisions. San Jose and Addition became entangled in land litigation and were lost, while the miscellaneous property was gradually sold or lost as well.
Henry Dalton was married in 1847 to María Guadalupe Zamorano, daughter of María Luisa Arguello de Zamorano and Agustín Vicente Zamorano. Dalton was 43 years of age, his bride 15. The couple had eleven children, seven of which outlived their father: Winnall Augustin, Luisa, Soyla, Henry Francisco, Elena, Valentine, and Joseph Russell.
Dalton had three major dedications during his lifetime after establishing himself in California: the welfare of his family, his fight to keep his lands, and his efforts to obtain an equitable settlement in his claims before the Mexican government. These Mexican claims arose out of two events: damages to property sustained during the Mexican-American war of 1845-1848, during which he not only was in sympathy with the Mexican cause, but placed a considerable sum of money and supplies at the disposal of the Mexican governor of California. He also suffered material damages, as well as the loss of livestock stolen from ranchos Azusa and Santa Anita, when the troops of Fremont and Stockton entered Los Angeles. The second event occasioning claims in Mexico stemmed from the purchase he had made in 1840 of the lands forming part of the estate of the Marques de Aguayo, but to which he had never been given either clear title or possession. The Mexican government readily accepted the validity of both claims, and made payment in bonds which proved to be unredeemable during Dalton's lifetime because of the precarious condition of the Mexican economy. Thus the Mexican claims, like the California land litigation lasted many years: the former from 1846 until after Henry Dalton's death, being continued by his heirs; the latter from the early 1850s, culminating in the loss of Azusa in 1881.
Dalton never abandoned the hope of recovering at least part of the lost lands, and attempted on several occasions to repurchase sections of his ranches. This was an ambitious project, since he was deeply mortgaged during the entire period of litigation, largely because of the expenses caused by squatter claims on Azusa after 1858, the date of the erroneous and detrimental Hancock Survey. The mortgages were held by F. L. A. Pioche, later by the Pioche estate heirs.
Many of the Dalton papers are personal, concerned with purely family matters. This aspect becomes even more accentuated after Dalton's death in 1884, and we are able to watch the separate branches of the family grow and develop. Marriages, births, divorce, death, joys and anguish, show through the family letters.
