Who is the Hufflepuff house ghost?

The Fat Friar proves that a house ghost can be happy, friendly, and well-meaning. He's welcoming to first-years and hopes that every student will be a Hufflepuff. Backstory-wise, he was executed after it was discovered that he could remedy the pox by pointing a stick at the afflicted.
