I'm not a fan of
Lionel, but mostly because I think of
Lionel Richie when I hear the name (which is no bad association, but still). However, I like, let's call them "lion names", such as
Leo,
Leon,
Leonas or
Lev.
I really like
Henry! This one is really "retro-chic" in my opinion, or how you may call it. I don't really know though whether I would actually use it myself. It still isn't part of my favorites - yet.
