Carter - very American but I quite like it. For a boy I presume?
Jude - not especially keen
Cohen - it's ok. A little awkward with surname but not terribly
Georgia - quite like it but much prefer Georgina
Callie/Calleigh - like it
Anya - really like it
Lucas - like it
Imogen - like it
Flynn - really like it but yeah, think it's too much with Freya
Maddie - lovely as a short for Madeleine or Madison but wouldn't use it on its own
Jenna - it's ok
Hunter - quite like it. Again, sounds very American
Nathan/Nate - really don't like Nathan but do love Nathaniel for some reason.
they're a VERY mixed bag so it's hard to suggest others. Ummm ...
