Which Northeast Indian peoples traditionally lived in longhouses?

The term "Northeast Indian" refers to the indigenous peoples of the North American culture area, not to peoples from Northeast India. Within the context of North American Northeast Indians, the Iroquoians were the primary group that traditionally lived in longhouses.1

These structures were roughly rectangular, featuring a framework of saplings covered with bark panels or shingles. Unlike the wickiups or wigwams used by Algonquian and Siouan groups, which typically housed a single family, the longhouse was designed to accommodate multiple families. Interior partitions divided the space into compartments, with a central aisle and a series of shared hearths running the length of the building. Depending on the number of resident families, these dwellings could range from 40 to 400 feet in length.21
