Union Togolaise de Banque Barrister James Maga Obtained my birth certificate and email address as well personal information not including my S.S. # thank goodness Internet

This person Barrister James Maga sent me a death certificate of a P. A. Manookian stating he left behind 5.2 million unclaimed dollars.  He initially contacted me through facebook and obtained my email address.  Is this real?  I have researched about fraud and read one similar report of the same person attempting to reach others through facebook offering the same amount of money with the same story.  Barrister James Maga has my full name, phone number, personal email address, and a copy of my birth certificate.  I am stupid for sending the birth certificate, but I did not send my bank account number nor have I sent any money through westernunion as the bank that contacted me asked me to do.  Am I in trouble with this person having the information that he does?  He does not have my S.S. # or driver's license but I am worried about the other information.  I have checked my bank account and nothing has been taken out so far.  Should I close my account and reopen a new one?  It's not like I have lots of money in there but what I do have is very important for bills.  The person's death certificate he sent me has my same last name and has the same initials as a relative who did die around the same time James Maga reported.  This is crazy.  I should have researched more before even acknowlegding this person.  It seemed legit because of the wording and the death certificate he sent.  He also asked me not to tell anyone and now I am scared as hell that I could lose what little I have with some sort of ID fraud.  I am already paralyzed and have so many problems that I deal with and this is the last thing I need for someone to steal my identity.  Please give me insight as to what I should do.  Should I close my email account, and bank account although no bank information was given?  I did read a report stating that people can use personal email accounts for fraudulent purposes, and I have no idea what this person could do with my full name and birth certificate.  At least I stopped when James Maga asked me for money.  I have all the emails saved from James Maga and from the bank that is supposed to give me this large sum of money.  Please advise me.
