In fact most people do not even know that Arch Bishop Benson Idahosa and his wife are Igbo from Igbanke in Uhuonde Local Government area of EDO state that was formerly in Orhionwon LGA .
The mother of the late Samuel Odaigbovo Ogbemudia is Igbanke!
Most indigenes of this town just like Ika people bear hybrid names that most often could just jolly well pass as EDO because of their names like Nduka Irabor, Jim Ovia, Omorogie Nwawanne, Collins Edumaruse etcDELTA STATE

19)The Igbos in Benue State particularly those in Ado, Oju, Obi and Okpoku LGAs of the state were in existence before the advent of Christian religion in Nigeria.
The Igbo found in Benue are: Umuezeokoha, Umuezeoka, Oriuzor, Umuoghara, Amaekka and Amaezekwe all in Ezza communities, Izzi, Ezzamgbo and Effium, these are the people who would have been in present-day Ebonyi State but due to the fact that the Nigerian government then carved them into Benue in order to suppress the population of the East. Apart from the Ezza-speaking clan, particularly the people of Umuezeokoha that has over 300 villages, if you are to calculate the number of Igbo-speaking villages in Benue State, outside Umuezeokaoha, you would be talking altogether about over 600 villages. Three of the biggest markets in Benue are all in the Igbo-speaking part.
The markets are Inikiri Ichari, Iddah, Iduokpe.
There are also some Igbo speaking Idoma towns in Benue State.KOGI STATE
20) THE indigenouse Igbo-speaking communities in Kogi state especially in Ibaji and Igalamela/Odolu LGAs are Eke Avurugo community,such as Nwajala, Umuoye, Ubulie-Umuez, ozara, and umuoye and many more.NOTE
The current Ooni of Ife, Oba Adeyeye Enitan Ogunwusi, Ojaja II, also told us that his kingdom was initially conquered by the Igbo (PLEASE KINDLY NOTE THAT HE WAS NOT REFERRING TO THE UGBO OF ONDO STATE)until they were rescued by Moremi and he also spoke of an aboriginal Igbo community that still exist in ILE Ife to this day.Source

The Ugbo people of Ondo State have the same Obatala linkage with the Aborigines of Ile Ife. Note: there are several Igbo towns in present-day Igboland that are called Ugbo.
For instance, you have Ugbodu in Delta State, and Ugbo in Enugu State, just to mention a few.
