Blennerhassett Island, the most famous of the Ohio River islands, was for countless generations the home of Native Americans. It first appeared in written records in 1766 and became immortal in American history as the 1805-1807 base of operations for Aaron Burr’s military expedition against Mexico. In 1797, Harman Blennerhassett, Sr., and his wife, Margaret Agnew, settled on this island, for eight years making it their home. Here in the wilderness they cultivated the arts, cared for their neighbors, and built a great home which became the wonder of its time.
