I personally think that using nicknames as names is alright. It's really just fun! I don't know why anyone would be upset.
Luke:
1.
Luke is a name that never went away. It's one of the oldies that are pleasing to the ear and simple. I don't know if it's popular currently, but it's definitely not going to be rare anytime soon.
2. I can see
Luke standing on its own. I never liked
Lucas that much either.
3. I think I would use another simple, classic name as a middle name. Like
Daniel,
Philip,
William and others like that. If you want something more fancy I would go with
Axel,
Atlas or Memphis. My final choice would probably be
Atlas, but that's just my opinion.
4. I think
Luke would be associated with
Luke Skywalker from
Star Wars a lot. It depends on you if you think that's bad or not. Other than that, I think it's a name that doesn't have any more associations. None on the top of my head, that is.
Lucy Kate1.
Kate is a little too popular for my taste, but
Lucy I can handle.
2.
Lucy. Just
Lucy is great.
3. I believe that having
Kate as a middle name makes
Lucy sound more common, if that makes any sense. Here are some other ideas: Erin/Eryn, Danai, Helene/Helena/Elena,
Justine,
Regine,
Noa, or
Min.
4.
Lucy could be associated with the movie
Lucy which came out sometime in the last few years, but it's a forgettable movie so that wouldn't be a problem. Other than that, it's a name that reminds a lot of us of
Lucy In The
Sky With Diamonds by The Beatles. As a person named
Jude, I don't find it that bad!
Good luck with the naming!
