The bank requires photo ID with the birth spelling...impossible.

The bank I just visited just suggested a "ONE AND THE SAME PERSON AFFIDAVIT," which I'd never heard of. What I need to have notarized, sworn, or whatever, is that "I, the undersigned, having been named with a first name spelling as indicated on my birth certificate, and whereas I have opted to use a different spelling of my first name most of my lifetime...do hereby swear that I am one in the same person."

The bank says they would accept such an affidavit, and be good to go with the account. Where would I find such a document?
