Families in Harry Potter

You might need to write down the entire name of some characters (first name + surname)

Characters refered as "Boyfriend/Girlfriend" have been called this way in the books or had kissed the character during a date. For example, Parvati Patil was just Harry's date for the Yule Ball (she's not his girlfriend) but Hermione and Viktor Krum were more involved in their relationship.

I apologize for any grammar incorrections since English is not my mother tongue. You may correct me in the comments. Thanks.
