John Nepomucene.

There's this one old (Catholic) church building in my neighborhood that has "John Nepomucene" engraved on the front of it, and the other week when I was riding on a train on a long-distance train trip, I passed by some church building that said "John Nepomuk" on the front of it, and all of a sudden I connected the two, as well as realized that that must also be the middle name of this one composer "Johann Nepomuk Hummel" who I hear about on the radio all the time, on this one classical music station that I listen to.
