Ernest George PRIDDEY born, as you say, in the 1st Qtr 1949 at Birmingham with mother's maiden name of HORRIDGE, but I have failed to find a PRIDDEY/HORRIDGE marriage anywhere at any date. Of the deaths in the Birmingham area between 1948 and 1958, all are men of age about 70 years. No female HORRIDGE deaths in the Birmingham in that same ten years either.
Do you happen to have a copy of Ernest George's Birth Certificate as that would at least give us the forenames of his parents?
Incidentally, neither relevant surnames appear in the online newspapers or on the Birmingham Electoral Rolls.
