“Does the registrar not provide ACTUAL certified copies, or just ginned up versions on current blank stock, purporting to be the original???”
Almost no place provides actual certified copies any more. They just provide a certification. Anyone with inside access to the state computers could conceivably fake that pretty easily.
I hadn't thought of the birth records being hacked - but I think that from the evidence I have heard is that their are lots of discrepancies on the form compared to those provided by the state.
One thing that hasn't been mentioned on this thread I don't think is that back in the day his race would have been “black”. Sounds like someone may have been a bit too fancy in trying to backdate the document by using “African”. (Personally, for 1961 I would have thought Negro or Negroid would have fit).
