First of all, most of the websites listed here gave his name in full as ""Chibuike Rotimi Amaechi"" and not ""Chibuike Amaechi"", including the official Rivers State Government website you provided. Even the very few references that call him Chibuike Amaechi also refer to him as Rotimi Amaechi at some point of the same article. A Google search of ""Rotimi Amaechi"" produces 74.89% more results than ""Chibuike Amaechi"" so I wonder how ""common"" is really defined. For every reference you provide that trivially use only ""Chibuike Amaechi"", there exist some 10 references that call him ""Rotimi Amaechi"". I have lived a good part of my life in Rivers State, and I never knew his name was Chibuike. I am willing to let sleeping dogs lie for now, but as soon as another editor finds the name inappropriate, I will step in to enforce consensus. Regards."
