Re: Boy name... only 3.5 months
Well, I love your children's names and almost all of your list! I really like Piers and think it goes great with your kids' name. I would not worry about Piers Morgan because kids won't know who he is at all and then by the time your Piers is an adult, I doubt Piers Morgan will be much of a prominent figure (and I don't think he is now either). And Piers Marten flows great!
