Third, the social classes described by Swanton were not classes or castes, as the terms are generally used in English, but exogamous ranked clans or moieties, with patterns of descent common to most Native peoples of the American southeast. Tribes such as the Chickasaw, Creek, Timucua, Caddo, and Apalachee were organized into ranked clans, with the requirement that one cannot marry within one's clan. Related to this theory is the idea that Honored status was not a class or a clan, but a title. Sun status, likewise, may not have been a class but rather a term for the royal family. If true, Natchez society would have been a moiety of just two groups, commoners and nobles. The requirement of exogamy may have applied to Suns only, rather than the entire nobility.
