Is anybody at Hogwarts married? Professors, groundskeepers, lunch ladies? (Joking about the lunch ladies.)
For however well we got to know the faculty of Hogwarts, I don't remember spouses or children being mentioned once.
I've never been to a school of witchcraft and wizardry, but in the schools I have been to, married professors are by far the norm, and it often comes up one way or another (especially if you know them for 7 or so years).
In contrast, Hogwarts faculty seem to have a Jedi Order vibe going on.
Does Hogwarts have any restrictions on marriage, or it is just coincidental?
