These names are subject to change, but they are the two we keep coming back to at the moment.
Violet
Pros: lovely name. Floral but not OTT. Timeless. Currently haven't met anyone wth the name. An 'almost-anagram' of DP's name.
Cons: worried it will be too popular soon. People associate with horrible Violet from Roald Dahl book.
Tamsin
Pros: Never met anyone with the name. Dainty but strong, will age well. My suggestion. Cornish name (Cornwall is a dear place to me, not so much to DP).
Cons: meaning of Tamsin is 'Twin.' I know I shouldn't get caught up on meanings but growing up with a name of uncertain meaning myself I've always liked meanings.
