I have family in Maryland. What Rocco did not mention is that this Church, Saint Alphonsus Church, is located not 700 yards from the Basilica. It is modeled on the Cathedral of Koln (where Pope Benedict was Bishop and that was the site of the last World Youth Day) and had St. John Neumann, a Bavarian, as its first Pastor before he became Bishop of Philadelphia. It is the site of the Tridentine Latin Mass I attended when I visited my family and it's gorgeous. There might be something to this story.
Now, St. Alphonsus is utterly beautiful!
I believe he was Archbishop of Munich. Did that happen afterward?
