Ok so just in deadly serious, death to the loser type battle royale fun, I am currently TTC and we have had many discussions about names we like and hate.
We are going to have a BIG problem, my DH is 20 years older than me and in most things I'm happy with how he see's life but not in the world of baby names.
I have a DSS who is 13 called Liam.
I like either really really really old names or american ones (not much difference), DH vetoes nearly all off them but doesn't actually add many suggestions himself.
So I love
Chase (would be number one without question) but this is a definate no, I may get away with it as a middle name.
Lucas - Both agree and goes with DSS, but so popular and I want something slightly different
Zacharia - Like, but DH used to have a sodding dog called Zac
Zane - possible, but then the middle name is a pain, because Zane Chase does not go.
Noah - Loved and vetoed
Isiah - Liked and vetoed
Girls names are even worse
DH suggested "helpfully"
Sharon and Tracy (which are fine, are not what I intend to use ever)
I suggested
Felicity - Loved and vetoed
Francesca - Loved and vetoed
Sophie - Liked but very popular
Lucy - Possible, maybe but still popular
Savannah - Loved and given the "look" didn't even warrant a veto 
Amelia - too popular
Mallory - Liked and vetoed
Cassiopia
So Mumsnetters what happens when you are a million miles apart in what you both like?
As I say this is tongue in cheek at the moment, but it's a right PITA.
