Vilton is part of the Kevin/Melvin/Milton trend, but since people want be original they make up all sorts of names that sound similar, but aren't quite those toplist names.
Wilton seems to exist, though (v = w in Swedish), but Vilton is just as likely to be
Vilhelm +
Milton.
Love (LOO-ve) is a very common boys name in Sweden, and so is
Neo (more recently), I doubt it's short for anything.
