Most of the professors during Harry's time at Hogwarts seem to be single, but maybe the lesser known ones like Sinistra were married during that time I'm sure a lot of them could make the long distance work, especially with letters and two-way mirrors and all that, and I feel like they would be allowed to visit their families every so often during the term, but probably still hard on the relationship at times.

I always enjoy trying to sort characters into the Hogwarts houses, so I also like imagining what houses these professors were in, assuming they went to Hogwarts. I don't think we were ever told what told house Charity Burbage was in, but I feel like I could see her in either Ravenclaw or Hufflepuff. And I feel like Binns is definitely a Ravenclaw
