Kin Groups and Descent. Catawba society was matrilineal at least until the early twentieth century. Extended Kinship groups were clearly important in determining an Individual's place in society—serving to protect one from harm, determining whom one could marry, and so on—but there is no clear evidence of clans.
Kinship Terminology. Efforts to fit Catawba kinship terms into an accepted kinship classification category have been unsuccessful. Fragmentary evidence, however, suggests that the Tutelo, a Siouan-speaking Piedmont tribe living near the Catawba in colonial times, followed the Dakota system.
