designs-The Lenape are also known as the Delaware Indians, which is also the name of a state and a river. The Matawans were a sub-tribe in the group of Native Americans that shared a common language, Lenape or Delaware. The Delaware/Lenape groups were decimated by European disease, such as small pox and measles to fighting with other groups making up the Iroquois Nation, the French-Indian War and the Revolutionary War, to white settlers invading their lands. I do not know if how many of the Matawans are left, or if they are represented in any of the Indian Reservations in the Eastern USA.
Sorry I don't have any more accurate numbers.
