Jacob Wright Harlan (b. 1828) grew up in Indiana and moved to Michigan where he joined an uncle who organized a wagon train to California in 1845. California '46 to '88 (1888) contains Harlan's memories of his overland journey to California in 1846, acquaintance with rescuers and survivors of the Reid and Donner Parties, Frémont's battalion in 1846-1847, San Francisco milk and livery businesses, storekeeping in gold camps near Coloma and Sonora, farming and ranching in and near San José, San Joaquín Valley, Alameda, and Choloma Valley. He then recalls his second overland trip to California, 1853, as part of cattle drive and real estate development in San Leandro.
