Hannah Stoddard joined her sister Elizabeth Huntington in Sacramento in 1851, marrying Collis P. Huntington’s business partner, Daniel Hammond, shortly after her arrival. The wedding, a simple ceremony attended by a small number of friends, was held in the Huntingtons’ home. Daniel Hammond and Collis Huntington had opened a store in San Francisco in 1850 under the name of Huntington, Hammond & Co. at 54 K Street. The two sisters, Hannah and Elizabeth, were advisors and supporters of their husbands’ business, and their marriages turned a business venture into a family business. Collis and Daniel dissolved their business partnership after a few years, but their relationship by marriage remained strong. Daniel was eventually given a job as bookkeeper for Collis’ Central Pacific Rail Road.
Daniel died of inflammation of the brain in 1868. Four years later, Hannah married John Haviland, a San Francisco merchant, in 1872. She outlived her second husband as well. Her only child to survive infancy, Scott Hammond, drowned at the age of 16 at the site of one of Collis’ railroad projects in West Virginia in 1870.
Hannah died in 1919, leaving the bulk of her estate to the University of California at Berkeley. Haviland Hall, constructed in the 1920s at UC-Berkeley, was named for Hannah. She is remembered in California as one of the state’s pioneers.
