The Cornish emigrations began as early as 1836. However, the main influx to the New World was 1850 to 1890. The best known, but not the only, communities grew up in Grass Valley California and Mineral Point Wisconsin. Migration continued into the 1930s. Others were in New Hamphire, Pennsylvania Colorado Utah and Nevada. These links may help.
