James Miller, of Irish descent, came overland to California in 1844 with the Stephens-Townsend-Murphy Party and in April 1845 arrived in San Rafael.[5] Then, in 1846 he purchased 680 acres (2.8 km2) of land from Timothy Murphy, grantee of Rancho San Pedro, Santa Margarita y Las Gallinas. The land encompassed present day Marinwood and a creek which was later named Miller Creek. He rebuilt an old adobe on a hill where the Miller Creek condominiums are located and called it Miller Hall. By 1862 Miller had 10 children, and in 1864 donated a 3/4 acre site next to Miller Creek to have the Dixie School built upon it. The building still stands but has been relocated in front of Miller Creek Middle school on Las Gallinas Avenue. It is on the National Register of Historic Places. James Miller died in 1890. The 1,084-acre (4.39 km2) ranch he owned at the time was eventually sold to the Sequeira family in 1935. The family tore down Miller Hall later that year. A portion of the Miller land was sold to Anthony Faustine (A.F.) Silveira, who had leased the property from 1900 to 1935. Silveira built his own home and dairy facility in 1935 on the east side of what is now the 101 Highway. Silveira, the founding president of Marin Dairymen’s Milk Co. Ltd. aka Marin-Dell, died in a ranch accident in 1937. His family continued the ranching operation, which still exists.
