Tabitha - DH hates it.
Violet - Same, but also when I say it I think of 'violent' (for some reason), and that puts me off. But I still think it's pretty.
Lily - Too common.
Isobel/ Isabella - Twilight/ popularity wrecked it for me.
And also couldn't use all of the above, as DD has quite a classical/ traditional but unique name (unique, not ewneek), so now the pressure is on to find another one for #2!
