babynames | help please!

My second kiddo is due in a month and a half, and we can't agree on a name for ANYTHING. :(

My first is named Samuel, but we just call him Sammy for right now. I liked that I can call him something cutesy while he's small, but also that he has a name to 'grow into', as it were. I want this for my second as well... which we're PRETTY sure is a boy (he keeps crossing his legs when we go to check though... hmmm!) so boy names are what I'm looking for. I already have girl names set in my head, so if we get a big SURPRISE at the end here, I'm not too worried about that.

So yeah. Boy names that are mature and can be grow into, but have cutesy-poo nicknames for baby/childhood. :) Our tastes are pretty old fashioned, so nothing too new or ultra popular if possible. Thanks!

ETA: WOW, didn't expect so many responses so quickly. :) I'm going to show this post to my husband when he gets off work and hopefully he'll see that the things I've been telling him are actually good names that people OTHER than me like and think of too! ;)
