Most names in English and quite a few other languages are derived from Hebrew or other cultures venering the monotheistic deity some people call "God". It is false to say names don't mean anything because that is how names are thought up. They usually want to give a quality to their child (and sometimes wish it were magically there and not evben nurture them to have such qualities.) Back then, it was venerance to whatever they believed to be divine, but it could be named for natural or emotional characteristics, also venerable in some cases like animism.
So people shouldn't be allowed to criticize your choice of a name for either yourself or your offspring because every name has a meaning. While Kwigibo didn't have a meaning, once that got created on the Simpsons, it got a new meaning.
Lisa or Makoto are both equally good names even if you're whiter than 2% milk. However, to avoid confusion, I'd rather call my kid Seiko (誠子) or Seisuke (誠介) to avoid the confusion.
And even Tarou-Jirou-Saburou-like unoriginalities exist in other parts of the world. X Y Senior, X Y Junior, X Y the third, etc...
