i'm 20 weeks pregnant with dd2, and we absolutely love dd1's name so are struggling to find a name that grabs us equally for dd2 and also struggling to agree. we like quite unusual but not outlandish names. middle name will most likely be 'fleur' and our surname has 2 syllables beginning with f.
names we are currently considering, in no particular order:
elowen
mairi
seren (this is a left over from the list with dd1, but i know that it is no longer that unusual)
arwen (i am not as keen as dh on this)
ianthe (i love this but dh is vehemently vetoing)
open to suggestions in the same vane too 
thanks
