Galena was established in 1809 between Big and Little Walnut Creeks as a mill seat. A natural ten feet drop in elevation in a narrow neck between the two streams provided an excellent route for millraces and water-powered grist and saw mills were soon in operation. Gilbert Carpenter, the founder of the village, came from Wilkes Barre, Pennsylvania, and was the first Methodist clergyman in Delaware County. His gristmill held the first church services in the area.
