I don't know. It's not my forte, but I'm very picky about the application of the name
Lily. I really only like
Lily spelled as
Lily (no double Ls). I also really like the name
Lilian and the variations with that. I'm not into names like
Lilibeth or Lilimae because they sound a little to country-ish to me, like Ellie-Beth or Ellie-Mae.
Lilifee though is cute. I'm not sure it's great as a first name, but I'm not an authority on names by any means. If you feel a strong attachment to it and you end up using it, I'm sure the girl you give it to will be meant to rock it.
Personally, I think it makes for a fun middle name or a cute family nickname. :D I hope that helps. I'm sorry I couldn't be more on board with this one.
