I know one beagle and one teenager named
Lucy. Among my friends, it had a surge in popularity after Across the Universe came out and the Beatles became popular again. I think the Beatles adds to it's popularity.
Lucy and
Jude. That's a big reason why I like
Jude or why I started liking
Jude.
I don't really like the name. I think it is too nickname-y to be a full name and I don't like the full names associated with it with it.
It is a strong name though.
Lucille Ball is a great namesake. I prefer it to
Lucia,
Lucinda, or any other variant.
