The Rhodes Family Papers consist of correspondence (1838-1877), Robert H. Rhodes diary (1848-1849), California ranch business records(1858-1898), and miscellaneous biographical and genealogical materials pertaining to the Rhodes, Smith, Pister and McDermott families.

Dr. Robert H. Rhodes, a physician from New York City, came to California in 1849. His cousin, Col. Elisha A. Rhodes (1791-1858), a widower, had earlier gone to Texas where he was appointed U.S. Consul(1838). There Elisha married a widow, Mary Kimball (1808-1893) of Houston, and they had two sons, Cullen C. (b. 1839) and Edward A. (b. 1841). Both Elisha and Mary Rhodes also had children by their previous marriages. One of Col. Rhodes' sons, William Henry Rhodes (1822-1876), later achieved fame in California as author "Caxton" Rhodes. Elisha Rhodes was incapacitated by a stroke during the late 1840s and his wife, Mary, went to California with William H. (1850), leaving her husband behind. In 1852 she returned to Texas and brought the entire Rhodes family to California, settling them on Windsor Ranch about five miles from Stockton. After Col. Rhodes' death Mary Rhodes continued to operate their ranch for many years. She was also active in prisoner relief work during the Civil War.
