You say you want strong and masculine and then you say you like the name Erwin? Does not compute.Just as long as it isn't Aiden, Aydin, or how ever the hell you wanna spell that wussy name. I'm so sick of that name. You have the show "Sex in the City" & single moms everywhere to thank for that name. Give him a strong, manly name. You have the daughter; it's daddy's turn. I've always liked the names Erwin & Luke. Those names sound like guys you'd want in your corner in a bar brawl. Also never been a bad looking Luke in history. Fact.
