What Native American group lived in Maryland?

The indigenous people living in the area that would become the colony of Maryland when European settlement began in the 17th century were members of dozens of tribes, within a larger general grouping by language of Algonquian-speaking peoples. In the southern area of the territory, including the Eastern Shore, the largest tribe was the Piscataway. They are often considered with, or within, the Nanticoke, who lived in the northern part of the territory and modern Delaware; they in turn were closely related to the Lenni Lenape of modern Delaware and Pennsylvania. Peoples living on both sides of the Chesapeake Bay were united into the Powhatan Confederacy based in Virginia. Susquehannock people also lived in or claimed territory that included part of Northern Maryland, Northern Virginia, Pennsylvania, and New York.
