Gelelemend, also known as Killbuck or John Killbuck Jr., was an important Delaware principle Chief during the American Revolutionary War. He supported the rebel Americans, known as Patriots. His name signifies "a leader." He became principal chief of the Lenape in November 1778, following the death of White Eyes. With White Eyes and Captain Pipe, Gelelemend signed the Delaware Treaty with the United States in 1778. Only after the death of White Eyes later that year, who was murdered on November 5, 1778, by an American militia officer, did Gelelemend become principal chief of the Lenape. By 1781, Gelelemend had been forced from power. He was commissioned as a colonel and helped guide Colonel Daniel Brodhead in an expedition to destroy the Delaware capital of Coshocton in Ohio, where he had lived and served as chief. Gelelemend had become a man without a country. He lived at Fort Pitt until 1785. Long interested in Christianity, Gelelemend joined the Moravian mission at Salem, Ohio in 1788. At the baptism ceremony, he took the name William Henry, supposedly to honor a man who had rescued him during the French and Indian War.
