What's in a name?

My wife recently gave birth to our second child, a little boy. We'll be going to get him officially registered later today, which is also when he legally gets his name. We've been using the name for weeks now, but it only becomes official today.

In a similar vein, I've been working with Dream Girl as the name of my second book for months, but since it hasn't become "official" through getting published, I can still change it. A recent search on Goodreads informed me that there are over 100 books with this title, most of which are romances. This clashes with some previous research, so I think that I'll need to go back to the drawing board.

I hope my new son Donald Trump Pettit doesn't mind all the time I spend trying to come up with a name for this second book. Wait - what's that you say? Donald Trump is already taken by someone famous? Well shit.
