This record on GRO has an additional entryPossibly worth the chance of buying the birth certificate of the Freda Smith registered Bham Mar qtr 1934. About a tenner or so through the GRO. Might not help but I can't see any other way.
This means a change was made after the original registration. So it might well be worth getting this cert. and seeing what the change was.
