I don't like it as a name for my child but it is a good book in the Bible.
I have no idea if John-David Duggar has a girlfriend or not. Depending on his age he may not even be allowed to have a girlfriend. If he's dating anyone it's probably one of the girls from the Yates or Bates (I can't remember) family that was on TV with them a few weeks ago when they went sky diving and paintballing.
