Any of the 'youngest' generation of the coven who rescued Jay a hundred years ago. He's been a bit of a permanent fixture around, probably babysat and helped with homework and spellwork, snuck treats like the coolest big brother/immortal firebird to ever exist. I'd really like it if Jay was close to the witches that are heading out to see the world, as it were (in their 20s) and also to any that might be living and working in NYC that grew up in the coven of any age. Obviously, they can tap him up for magical feathers whenever the want too, which is...handy?
Honestly, since their great-grandparents took him in, this is Jay's only family right now and so I'd love to have some in game!
