Because queens consort lack an ordinal with which to distinguish between them, many historical texts and encyclopedias refer to deceased consorts by their premarital (or maiden) name or title, not by their marital royal title (examples: Queen Mary, consort of George V, is usually called Mary of Teck, and Queen Maria José, consort of Umberto II of Italy, is usually called Marie José of Belgium).
