 The Iroquois lived in long houses, primarily in what is now New York, and had a strong confederacy which gave them power beyond their numbers.To fill the void left by the demise of the Susquehannocks, the Iroquois encouraged displaced tribes from the east to settle in the West Branch watershed, including the Lenape (or Delaware).The Seneca, members of the Iroquois Confederacy, became inhabitants in the area of Black Moshannon Lake, which was a series of beaver ponds at the time.
