Many historians today consider Blennerhassett Island to be the most historic site in the state of West Virginia. Even if Harman and Margaret Blennerhassett and Aaron Burr had never set foot on the island, it would still be a rich kaleidoscope of history because every era of its past contains colorful and exciting events. Its historical worth, in fact, was recognized at an extremely early date. As early as c. 1830, three different Ohio Valley writer independently wrote of it as having become “classic ground” because of the history that had transpired there.

There follows a brief sketch of the Island’s past, giving, by subject, some of its more important aspects:

Native Americans

Blennerhassett Island is ranked as one of the richest Native American archeological sites in the American Midwest. It was inhabited by aborigines as early as 9,000 BC. The first archeological expedition arrived on the Island from the Smithsonian Institution in 1882. Since then, archeologists have recovered many beautiful Native American artifacts from the island’s soil, such as arrowheads, spear points, pottery, jewelry, tools and carved stone pipes.

In the 1760s, the island was home of one of the most famous Native Americans in colonial America, the Delaware chief, Nemacolin. He died on the island in 1767.

Early White Settlement

Three famous Ohio Valley Indian rangers lived on the island in the 1780s and 1790s: Joshua Fleeharty, John James, Jr. and Moses Hewitt.

The Armstrong family massacre took place on nearby Virginia shore in 1794 ~ one of the bloodiest and best recorded Native American raids in Ohio Valley history. Some of the Armstrongs fled to the island for protection. The island itself was raided twice during the 1791-1795 Indian War.

It was painted and sketched by many artists, including Howard Chandler Christy and the famous Philadelphia landscape artist, Edmund Lewis.

The gardens contained long, large hothouses where there grew orange, lemon, fig and citron trees. The Blennerhassett flower garden was the finest one west of the Alleghenies. One of the orchards on Blennerhassett Island was planted by John “Johnny Appleseed” Chapman.
