We found boy names to be sooooooo much harder to come up with than girl names. (We never found out gender ahead of time, so always had options for both.) It's hard to find one that was the perfect balance of unique but not weird; not too trendy; masculine without being hardcore; and little to no chance of moving into the realm of girl names - since once the girls take over a name, there's no going back! 

Oldest son is Elliot Brett, though he was a tiny, tiny smidge away from being Nathaniel. Named after DH, Brett. Younger son is Jonah William, named after my dad who was John William.  Third child (ended up being a girl) boy name was Zachary Charles. Or might have ended up as Nicholas.

For girl names, the first time we'd picked Laura Celeste. Second time, he would've been Laura or Meredith Celeste. Third baby ended up being Audrey Celeste. (Celeste is my middle name.)
