Which Native American language families were spoken in the Northeast culture area?

At the time of European contact, the Northeast culture area was occupied by indigenous peoples who primarily spoke languages belonging to three distinct families:

• Algonquian
• Iroquoian
• Siouan

While the traditional languages of the region are most frequently associated with the Algonquian and Iroquoian families, historical records from the 16th century confirm that the Siouan language family was also present within the Northeast culture area.12
