Also, I understand the requirements for birth years but what type of proof is required to have one removed?

This question has to be split up into two parts:
a) How to document?
Either you document, that the BY is wrong and assign another one (here a recent example) or you document that there are only entries for one person with the name (often after a common name was established or changed as seen here). Any invalidation should be documented in this thread.
b) How to get it out of the online data base?
Open a support ticket. At least in the past this worked.
