<p>Just wondering.</p>
<p>Good question. Probably, assuming you are inquiring about boarding schools, Portsmouth Abbey School, Portsmouth, Rhode Island. I do not know for certain, but there may not be many Catholic boarding schools as it may be thought of as "breaking up the family" too early. Just a guess, though.</p>
<p>Canterbury or Portsmouth Abbey.</p>
<p>Gilmour Academy near Cleveland is excellent. It is mostly day, but has a small boarding population.
