I love surnames as first names and I remember really liking Cooper when you first posted about it. There are so many surnames that are now used as first names: Harrison, Curtis, Harvey, Riley, Ford... Even traditional first names are often surnames too: James, George, Michael... DH and I have deliberated many - it's so hard to find names you both love. Currently we have 2 possibilities for a boy: Leo James or Harvey James. For a girl, there are several that we like (Carmen, Anais, Lauren, Cleo) but we always seem to come back to Ada. Possibly Ada Kate. We know Ada will not be to everyone's taste (my mum turned her nose up which spelt the end of her being involved in further name conversations!) but we both love it. Good luck with Cooper, I think it's a great name x
