Here are the answers:

1. Colman of Stockerau. There were several saints named Colman, none of whom have anything to do with mustard.

2. Barbara. Also the patron of artillery people, fireworks, explosives, and so on. I do not know how she was associated with hats.

3. Michael. The Archangel. Also soldiers, Marines, and parachutists.

4. Gervase. His brother, who was killed with him, was named Protase. To me they sound like amino acids.

5. Anthony the Abbot. Not to be confused with Anthony of Padua, Anthony the Great, et al.

6. Paul (nee Saul) of Taursus. The guy who wrote all those epistles.

7. Drago.

8. Joan of Arc, a/k/a La Pucelle. There is some evidence that she really wasn't burned and was later given a pension by Charles IX.

9. Neot.

10. Fiacre. He's also the patron saint of hemorrhoids, and for that I think he should also be the patron saint of computers.
