Boy Names

Kristel
Alright ladies, I'm 9w3d and since before I even conceived, DH and I have had a girls name picked and prepped.
But...my mother did the old 'needle over the belly' trick and it came out boy. It seems strange that I never considered a boy. Probably because DH wants a girl in the worst way.
However, I need to consider the LARGE possibility that I'm having a boy and I'm stuck.
I have a few that I like but I need some advice.
How did you pick a name?
How did you know where to start?
