As of 5:12pm on Tuesday, February 12th, I'm an uncle again. Woo Hoo! John David II aka Jack aka Deuce. My brother wants to know if there is a Saint Deuce. His wife isn't thrilled. About the Deuce alias not the Deuce himself. Here is Deuce with his big sister, Libby. From some basic browsing of Catholic Encyclopedia at newadvent.org, we find a couple saints.
Saint Deusdedit- archbishop of Cantebury d.664
Saint Deusdedit- Pope d. 618
