Sassoonan

Sassoonan or Allumapees (c. 1675 – 15 October 1747) was a Lenape chief who lived in the colonial-era Province of Pennsylvania in the late 17th and early 18th century. He was known for his negotiations with the provincial government of Pennsylvania in several land purchases. He was a respected leader until political intrigue and migration of the Lenape into the Ohio Country diminished his influence. During his final years he became dependent on alcohol and died in Shamokin in 1747. After his death the Lenape were without a chief until 1752, when the Iroquois leader Tanacharison appointed Shingas to represent them at the Logstown Treaty conference. He was a son of Tamanend, also known as "Tammany," a well-respected Lenape sachem known as a lover of peace and friendship.

After 1728, Sassoonan is often referred to as "Allumapees," (sometimes written "Olumapies," with a variety of other spellings). According to one source, this was actually a title, not a proper name: "Olomipees meant 'preserver of the records,'" and was given to "a head chief of the Delawares." A few sources also refer to him as "Weheequickhon," or "Wikwikhon," although this is disputed and the name may refer to someone else.
