The Cha'hta nation is formally, though not locally, divided into two íksa (yéksa) or _kinships_, which exist promiscuously throughout their territory. These divisions were defined by Allen Wright as: 1. Kasháp-úkla or kashápa úkĕla (ókla) "part of the people;" 2. Úkla inhulá'hta "people of the headmen."
