I like but am unsure about for reasons as mentioned:
Tristan (too sad)
Rory (a bit popular here)
Jack (very popular!)
Jasper (but surname ends in -er so no)
Heath (but with our surname sounds very similar to Heath Ledger... Which we don't want)
Leo (popular again)
Winter (but will be a spring baby!)
Soren (dh vetoed)
Gabriel (dh vetoed)
Rowan - dh is thinking about...
Dh is very picky. He did consider all of the above as possibles, except Jasper, Sioren and Gabriel which he vetoed, and Rowan he isn't that keen on. I might choose something a little more unusual but dh doesn't want anything too weird or even possibly in any way pick able on, it's hard work! Though he had agreed with Winter, strangely. He doesn't want a Hebrew name either because he thinks people will 'make assumptions about our religion' (which I think is nonsense... And does it matter?! Anyway...)
He likes Jack, Rory, Tristan, Ethan, Dylan. I would rather something more unusual than Jack/Ethan/Rory. He has vetoed Gabriel 
If it helps these are girls names I like (to show my style of names):
Felicity - dh ok
Hermione - dh unsure due HP connotations, though likes the name
Oriana/Ariana - dh unsure
Leila - dh ok
Nia - dh not keen
Genevieve (Ginny) - dh ok
Briar - dh vetoed
Ottilie (Tilly) - dh vetoed
Thomasina (Tommy) - dh vetoed
Does that help at all? Ultimately we will choose one of the popular names we like if we can't think of anything, but I feel a tinge of disappointment at the moment that we can't find the perfect name.
