Galena" is Latin for lead sulfide. In the peak year of 1845, the mining district, with Galena as its hub, produced almost 85% of the nation's lead. The "Lead Rush" preceded the California "Gold Rush" by 20 years. Galena claimed 9 residents who reached the rank of General for service rendered during the Civil War.
