Who’s Who in the Cooper Molera and Diaz Families
John B.R. Cooper (1791 – 1872)
Sea Captain, Merchant, and Immigrant
Captain Cooper went to sea when he was 14 years old. In 1823, his voyages brought him to Monterey, which was a part of Mexico at the time, where he met and married Encarnacion Vallejo and became a naturalized citizen of Mexico in 1830. He built the Cooper Adobe, operated a general merchandise store, and continued his trading expeditions to Hawaii and China. Cooper was granted vast ranchos from Sonoma to Big Sur where he raised cattle and built California’s first power-operated commercial sawmill in Sonoma.
Encarnacion Vallejo (1809 – 1902)
Devout Wife and Mother
Encarnacion Vallejo grew up in Monterey with her parents Ignacio and Maria Vallejo and nine brothers and sisters. When she was 18 years old, Encarnacion married Captain Cooper. She raised their children in the Adobe while managing the family’s affairs during her husband’s long voyages. Captain Cooper deeded the Cooper Adobe to Encarnacion in 1852.
Mariano Guadalupe Vallejo (1807 – 1890)
Military Commander, Politician, and Rancher
Mariano Vallejo was Encarnacion de Vallejo Cooper’s brother. Born in Monterey, he entered the military in 1823, served as the Commander of the Presidio of San Francisco in 1833, and founded the town of Sonoma in 1834. He was named Comandante General of the “Free State of Alta California” in 1836, an appointment eventually confirmed by the central government of Mexico. After California became a part of the United States, Vallejo was a delegate to California’s Constitutional Convention and was elected to California’s first senate.
Juan Bautista Alvarado (1809 – 1882)
Politician, Businessman, and Historian
Juan Alvarado was Encarnacion de Vallejo Cooper’s nephew. Alvarado traded the El Sur Rancho to Captain Cooper in 1834. The family ranched this property for decades until Frances Molera sold it to the Nature Conservancy in 1965 for what eventually became Andrew Molera State Park. Alvarado served as the governor of Alta California from 1836 to 1842.
Thomas Oliver Larkin (1802 – 1858)
Businessman and Politician
Thomas Larkin was Captain Cooper’s younger half-brother. Born in Massachusetts, he joined Cooper in California in 1832 as his clerk-assistant. He went on to become one of Monterey’s leading businessmen and was named the first and only US Consul to Alta California.
Anita Cooper Wohler (1828 – 1912)
Advocate for Spanish Culture
Anita Wohler was Captain John and Encarnacion Cooper’s oldest child. She married German-born Herman Wohler and they made San Francisco their home. In 1900 she bought back the Diaz Adobe and Spear Warehouse, consolidating the entire Cooper property. Upon her death she willed the complex to Frances Molera.
John H. Cooper (1830 – 1899)
Politician and Rancher
John Cooper was Captain John and Encarnacion Cooper’s oldest son. He attended missionary school in Honolulu, then was taught by private tutors at home in Monterey. Following his father’s death, he managed the family ranch lands which comprised over 17,000 acres, making Cooper one of the largest land owners in the state. John H. Cooper served as a Monterey County supervisor for nine years.
Amelia Cooper Molera (1844 – 1918)
Rancher and Philanthropist
Amelia Cooper Molera was the daughter of Captain John and Encarnacion Cooper, and the direct descendent to bring the Molera name into the family.

Eusebio Molera (1846 – 1932)
Engineer, Politician, and Scientist
Eusebio Molera moved to the United States after graduating from university in his native Spain. As an engineer, inventor, and architect, Eusebio was a true Renaissance man. He supervised the construction of several lighthouses in California. While working at the Point Sur Lighthouse he met and married Amelia Cooper. He served on the San Francisco Board of Supervisors, was president and director of the California Academy of Sciences and was a noted scholar.
Andrew Molera (1877 – 1931)
