Nah, he has ties to a Catholic HS from the same diocese. Al Bundy's portrayer has ties to the HS across town from Stoops'. Incidentally, St. John isn't officially under the umbrella of the Diocese of Youngstown, but it operates with the diocese's blessing.
You had me going on the first sentence; because I always thought the Heralds were their own deal. Now it makes sense.
Many moons ago, St. John (later known as Ss. John and Paul) was part of the Diocese of Youngstown. No idea if the school went off on its own to avoid being closed by the diocese or what, let alone when it happened, but I remember that the school seemed like it was always on the verge of being closed by the DoY. DoY is comprised of: Ashtabula, Trumbull, Mahoning, Columbiana, Portage, and Stark County.
