DP and I want to get married at some point in the future.
DS has my surname. DP wants us all to change to his surname. DS is the last person in our family with the surname so I don't want to change his and I don't want to have a different name to him either. DP thinks because it is a common surname I'm being silly about not wanting to change DS' name just because he's the last one in the family with it.
I also don't see why the woman has to lose her surname and take up the man's.
I said I was willing to compromise and perhaps double barrell my surname and DP and DS can keep the ones they have now.
DP doesn't like double barrelled surnames. He's into tradition massively and doesn't think you should just invent a new surname.
However I've heard from a few people interested in family history that the joining together of 2 surnames is not that new, it is the insertion of a hyphen between them that is a more modern idea.
