The German Reformed Church was organized on Kelleys Island in 1865. The congregation built this church from island stone in 1866 on ½ acre of land purchased from Alfred S. and Hannah Kelley. By 1871, the congregation, one of five on the island, heard services in German and had 25 families as members, including those of Baumler, Beatty, Becker, Boker, Burger, Cattenach, Dodge, Elfers, Fischer Gerlach, Hess, Jordon, Keifer, Lange, Nowalk, Pringnitz, Huber, Renter, Schaedler, Scheele, Smith, Stoll, Suhr, and Trieschman. Rev. A. William Von Kaske was the congregation’s last resident minister, leaving in 1915. The church’s final service, funeral for William Burger, was held in 1942. The church’s Ladies Aid Society was able to maintain the building until 1957, after which it was left vacant. The Kelley’s Island Historical Association leased the church in 1981 and was granted the deed in 1986.
