I like older, unusual names, Millicent, Pearl, Agatha...etc.
DH likes McKayla, Kayla, Kendra even though his cousin who we see a lot is Kayla and it's a very popular name around here.
It's the same with boy names. I got away with naming DS Donald James because it's a family name, but finding something we both like, that goes with DS is not easy and ends in frustration.
Re: Husband and I have very different tastes
We have a similar problem: he likes very traditional common names, and I like names that are a bit rarer (but not weird). We have very little overlap. In fact, we talked girl names this weekend (we're team green) and between our two shortlists, we have one overlap, and it's at the bottom of both shortlists!
Our strategy at this stage is to chat about it and then leave it for a while. I keep expecting the baby to have an "obvious" name when we meet him/her.
