We like classic, but not too common names. British feel is a bonus.
I personally love Sasha and Maya, but can't use them due to a niece and a dog having them!
DH has suggested Leila, but i think that's increasingly common.
Do Americans know how to pronounce Cosima?
The children all have/will have middle name similar to Hutchins and last name similar to Barr, so no "G" names to avoid initials GHB, but otherwise most names seem to work.
