IGBO bu ofu!: How can a man from Benin bear Igbo Name?

Yesterday night, a coordinator in a family of IPOB in Spain called Radio Biafra, his name is Mr Isioma from umunnede (Delta state) he said something that prompted my article this morning.

He said how can somebody say I am not Igbo we migrated from Benin and I keep asking them why is our villages, communities and Towns names Igbo? Why is our family names Igbo? Why do we bear Igbo names? I mean Benin is very close to us than the five state Igboland why is it we don't speak Benin how did our forefathers start speaking Igbo? Up till now no one has come up with any answer, there's no history that Igbo ever invaded our land or colonized us rather there are uncountable accounts of war and invasion between us and Benin which caused us to have a pinch of Benin origins among us.

I have tried as much as possible to avoid the debate of where the Igbos in Delta state migrated from but because I don't care! If they like let them come from Zamfara wetin concern me, I mean how can educated person still be deceived in this time and age with the garbage of Benin ancestry. it is very very shameful.

 I have come to the conclusion to believe the story which says that the man ezechima or Ezechime was an Igbo man who migrated to benin for greener pastures and multiplied even married Benin women adding to the ones he already married he prospered to the envy of his host some of his relatives and relations joined him and eventually war started, he relocated back to his land occupying the place very close to benin with his people who later joined him.
 I don't want to quote any book written by the same people who are responsible for distorting the history of our people.

How can a man from Benin bear Igbo Name? Ezechima or Ezechime.
I understand that Benin kingdom through wars installed kings of the people who helped them win their people and those families were made to swear oath of allegiance to the Benin kingdom  forever.
 Your name is Obi of Issele-Uku (Oligbo) His Royal Majesty, Obi Nduka Ezeagwuna (25 years old) and you went to benin shamefully and ignorantly said your people migrated from Benin, what nonsense.
Please tell us how your name instead of Osaro you are Nduka.
 Until then, we can't debate the TRUTH that you are IGBO. Deal with it!
I rest my case!
