Cornwall, England's western-most county, is one of six Celtic nations that include Ireland, Scotland, Wales, the Isle of Man, and France's Brittany, each sources of immigrants to Nevada. As early as the Bronze Age, Cornwall's tin mines won fame, but failure of Cornish mining in the 1830s inspired immigration to other centers of mineral production. About 100,000 Cornish left a county that had a population of almost 370,000 in 1861.
