Two questions I had about the Harry Potter universe:
1) Could a person reproduce with a house elf, and would it be considered a pure-blood, assuming it's wizard/witch parent was one?
2) Where did Hermione learn magic before Hogwarts? She doesn't have magical family, so she couldn't learn it from them. I assumed that there were tutors that taught magic to remedial students, and those that never graduated. The last is effectively a GED course for magical drop-outs.
