Welcome to The Historical Society of the Cocalico Valley

     The Historical Society of the Cocalico Valley (HSCV) invites you to explore the following pages and, better still to visit us in person, to discover the fascinating heritage associated with this area of Lancaster County, Pennsylvania.

     The HSCV was formed in 1957 as a project of the Ephrata Recreation Center. In 1961 the Society purchased the beautiful Victorian Italianate Connell Mansion built in 1869. That structure now houses the three-story, thirteen-room Theodore Sprecher Museum. In 1989, the Society purchased the adjacent English Tudor-style home and converted it into the William and Jemima Brossman Library and Research Center at the Hamaker House.
