Guignole is, yes, who the theatre in Paris was named after. St. Quentin has a prison in California named after him. St. Fiacre is also the patron of Parisian taxi drivers. There is another prison in St. Cloud, Minnesota.

If all of these bother you at once you could try St. Jude, patron of the impossible. Go for St. Christina the Astonishing if you think you have all of them at once -- she's the patron saint of psychiatrists (if you read about her you'll understand why).
