Personally, what I've realised through interacting with anioma people (the nicest person I know on earth is my aunt from onicha-ugbo) is that Anioma itself is a communion of different tribes of which the major ones are Igbo, Ukwuani, and Ika. The Ukwuanis or Ndokwas, and the Ikas are usually the ones who refute the idea or conception that they are Igbos, and truth be told, bini influence is easily noticeable in their dialect and culture. The seemingly more populous Aniocha, Oshimili people and some others are the ones correctly known as the Igbos/delta Igbos, and from my experiences, well over 70% of them see themselves as full Igbos without any other added nomenclature like Ika or Ukwuani. All these are my opinions based on my interactions with Asaba and Onicha-Ugbo people. Thanks guys....
