I like Curran, but it's a bit similar to Rowan (plus, just ran it past DH and surprise! he doesn't like it). It's funny how I keep coming across names that sound similar to Rowan - Warren and Cowan were two recent ones - and then going "Oh, wait, no". I guess it shows that we chose a good name for DD, anyway! :p
Just ran another list past DH this morning. It included Emrys, Heath, Gresham and Alcott, as well as a few he'd previously vetoed but I was hoping I could sneak back in for a second opinion. :p He vetoed them all. *sigh* And the others I ran past him from this thread? Fionn and Rhys and so on? Yeah, not so much.
He has made one recent suggestion - Wesley. It's not awful - I like the Princess Bride association, and Wesley from Buffy was (eventually) extremely awesome; but I can't get over the Wesley Crusher connotation. (DH said "Wesley Crusher was cool". I'm having children with this man??). Plus, I don't like Wes as a nickname. So there that is.
Our current contenders seem to be Miles, Lewis and Liam. Miles is the one I'm still iffy about; Lewis, likewise; and Liam I love, but it's the super-common-in-NZ-last-year one. So.... arrgh. I don't mind any of them, but.... but but but!
