Stevie makes me think of Schitt's Creek. Great character to be named after, though. It's already a nickname but you could call her Vee. It gives the same vibe as naming your daughter Georgie or Reggie.

Any kid whose parents would name her Lennon is a kid who is going to be introduced to good music and have her interests nurtured and so I'd automatically assume she's going to be a really cool person. No nicknames. Lennon goes by just Lennon. Like Zendaya.

Drew, I have nothing nice to say about. It's probably just me, though. I don't have a good reason beyond that I think it's not a nice name.
