Like many of Ozaukee County's cities and villages, the Village of Grafton has rural roots and began as a mill town. The German and Irish immigrants who settled in Grafton in the 1840s utilized the Milwaukee River as a source of hydropower for gristmills and woolen mills. Manufacturing grew and prospered in the village in the 20th century, including the Paramount Records studio and plant, which was in Grafton from 1929 to 1935. Paramount was one of the first and largest producers of blues and jazz records marketed to African-American consumers. Paramount's role in Grafton's history and Blues music history earned the village a spot on the historic Mississippi Blues Trail.
