The most important immigrants in early San Francisco were the Irish, according to historian Jeffrey Burns. “By 1856, more than 6,000 foreign born Irish -- comprising 12 percent of the city’s population – had arrived in San Francisco, growing to over 30,000 by 1870. By 1880, foreign-born Irish and Americans of Irish descent accounted for 33 percent of the city’s population. Irish filled the ranks of the police and fire departments and provided a significant portion of the city’s civil service employees.”
