Father Matthew Charles Kelly was one of the first and most influential Catholic priests to serve in Wisconsin. Father Kelly designed and built numerous churches and schools throughout the state. He was educated at Somaschi Fathers' School, Lugano, Switzerland and served as a Dominican novitiate from 1823 to 1828. In 1828 he migrated to the U.S. and completed his studies in Cincinnati, where he was ordained a priest in 1830. The same year, he was assigned as a missionary at Mackinac Island and served in Michigan, the Upper Peninsula, Green Bay and southern Canada.
