Has no one ever written Ron's aunt Tessie as Lucretia Black? I have looked all over and can't find anything.
She fits the position according to the Black family tree and what we know about Ron's family. Plus being a Black, especially a girl and one of the younger in her generation, owning a coastal house with her husband would be normal. Plus Tessie leaves Bill the house, meaning it is unlikely she ever had children - something Lucretia and Ignotous also never had.
The most valuable piece for this argument I find in her name itself ... Tessie isn't really any kind of name... While there are a few with it, it is more often a nickname. And people LOVE nicknames that don't sound anything like the real name during the time when she would have lived : James=Jim, Richard=Dick, William=Bill, ect.
Anyway, she plays a part in one of the chapters I'm going to be working on and the thought occurred to me that I have never seen this particular naming trope for her.
