The Igarras (Etuno), the Igbira Tao and the Igbirra Kwotos were believed to have migrated from the same area – Igala Land; the exact place is not yet known but it is believed not to be too far away from Idah – the headquarters of Igala Land.
As said earlier the Igarras (Etuno) are descendants of Igala/Okpoto union. They left the place because they were rated second class citizens and were therefore not accorded the same status as the Igalas. They had lived in Igala land for more than a century and had to leave because of the aforementioned reasons. This was early the 5th century about 1400 AD.
According to the dictates of the Oracle, they journeyed northwards so as to avoid the over-flooded Rivers Niger and Benue. Their first stop-over was in a place believed to be the present village called Oguma, near the bank of River Benue. They settled here for a reason awaiting the recession of the River Benue. They later crossed the River Benue through a place believed to be the present Umaisha. They did not settle here but those that could not continue with journey as a result of sickness and harsh weather were forced to settle in the present sites of Oguma, Umaisha, Kotonkarfi and their environs. These were mainly in the third group of the migration believed to be the Igbirra Kwotos.
