Manuel Castro, who presented this collection to H. H. Bancroft in 1875, was a member of a very well-known
California family. He was born in 1821, the son of José Simeón Castro and
María Antonia Pico Castro. Pío Pico was his uncle, José Castro his
cousin. His career began about 1839, and for more than a dozen years he was very active in government
and military affairs. After the revolt against Governor Micheltorena, in which Castro was prominent, he
became prefect of the Monterey district, a position of considerable authority and responsibility. He
took part in the difficulties with Frémont and in the Flores revolt, and in 1847 went to
Mexico with Flores. For some years he was in the military service there, acting for a time as head of
the military colony at Santo Tomás in Lower California. After 1852 Castro lived for the most
part in San Francisco, although he remained a Mexican citizen.
