The settlement at Akpa was difficult for many years due to hostilities with neighbors. After the death of Ukpaghiri, Mbiriba and his group moved to Usukpam and stayed there for many years but were never at peace with the neighbors. Mbiriba decided to move to Udara-ebuo whereas Otusi led the other branch of the family down stream and eventually founded Arochukwu. The term Nwajim is often used between Abiriba and Arochukwu people because of our common lineage. Mbiriba who had advanced in age, moved his group once more and settled at Udara-ebuo.
