Mambila
The Mambilla or Mambila people of Nigeria live on the Mambilla plateau (in 'Sardauna' Local government area of Taraba State in Nigeria). A small fraction of Mambilla migrants left the Mambilla Plateau for the Ndom Plain (also known as the Tikar Plain) on the Cameroon side of the international border as well as in a couple of small villages, such as New Namba, further north towards the towns of Gashaka and Banyo. The preferred ethnonym is spelt Mambila in Cameroon and Mambilla in Nigeria. "Norr" is also used (the word for person in Nigerian dialects of Mambilla)(Bami-Yuno, ms).
