Is there a Saint Murphy

There isn't a real Saint Murphy. 'Saints' are persons canonised by the church and, according to church theology, now live in heaven and can help people on earth. Sometimes people call a living person a saint, but this just means a virtuous person, and is not the same as a heavenly, canonised, 'Saint'. Someone has described a 'Saint Murphy', in Saints of the Fifth-Dentists.
