Azalea

This is a story of a tangled family. Two witches, one muggle. A nephew, as well. How did Harry Potter end up with magic-hating Petunia if he had another aunt that loved magic? (Aunt Petunia never mentioned her, so maybe she studied beetles, or wrote salacious novels, or was an actor.) (Severus Snape preferred her to Petunia, so maybe she was horribly strict.)
