Remus/Sirius Small Gifts

I do think of Andromeda and Ted being rather like that. But my head canon for the name is that there was a witch called Nymphadora from an old pureblood family some time back in history who broke with her family and tradition and made a very important contribution to magic in some way, maybe in curse-breaking - something very anti-dark that the Black family would have disapproved of. Being a woman, she didn't get much mention in the history classes, but Andromeda found a book about her in the Hogwarts library and read it as a teenager. That witch became her hero and she therefore named her daughter after her. I've never used that head canon in a story, but it's there in my head when I write the character (a lot of stuff I work out for my characters never makes it to the page).
