Underground railroad - This photo in Sandy Williams' book, "Images of America - Hinsdale," is of Graue Mill. "Due to its location, access to transportation and antislavery sympathies, Fullersburg served as a stop and transfer point for fugitive slaves traveling the Underground Railroad. Graue Mill harbored runaways and it is believed that Castle Inn (near York and Ogden) also sheltered slaves on their journey to freedom. Some residents recalled seeing wagons or sleighs stopping to unload disguised human cargo."
