Character Name: Thisbe Diana Holloway
Age: Seventeen - Date of Birth is the 28th of February, 1979
School Attended: Hogwarts
Current Year: Six
Ravenclaw: This is her house, so naturally Thisbe would know a lot of people from there. She spends quite some time in the common room, even though she is shy. But she does open up more once she knows someone, so yeah Ravenclaws. She would be more likely to interact with the ones around her age though, unless she tutors some younger kids.
Sixth Years: These would be the people she shares classes with, and by now she'd know them pretty well too. The classes she takes are in her profile, which can be found by clicking her signature. So classmates would be really cool.
Liverpool: This is where her family lives and has always lived, so any neighbours or people who live nearby, perhaps. They could know the Holloway family, and therefore Thisbe.
London: Her eldest brother Raphael lives in a flat in London, and she spends a lot of time bunking over there during the holidays, because her family tends to fight a lot and Thisbe likes to get away. So she knows the city pretty well, and could perhaps know a few people who live around there? Her brother is also a Healer at St. Mungo's, so she could possibly have been there with him a few times and run into someone.
Future/Actors: Thisbe keeps her family happy by being the perfect academic, but what she actually has a passion for is the stage. In the future, she tries to get into the theatre business, so anybody involved in that who could likely be a connection? I know it's a bit far, and it'll only happen a few years from present time once Thisbe has already graduated, but I still thought I'd put it out there.
Other Notes: Her profile can be accessed by clicking the signature, give it a read! Also, I'm open to other options that I may not have listed here, so throw me your characters! :)
