Conococheague Institute

The Conococheague Institute is located on historic Rock Hill Farm near the village of Welsh Run, Franklin County, Pennsylvania–about halfway between the Boroughs of Greencastle and Mercersburg.
Established in 1994 as a non-profit corporation, the Institute maintains five historic buildings, a 6,000 volume research and genealogy library, and more than 20 acres of scenic farmland, wetlands, meadows and trails/woodlands.

Effective December 2012, we will no longer maintain this website. Please find us on our new webpage, conococheagueinstitute.org.
