Combined surname

[Starfish]

I think its a good idea. Only problem I could see is if anyone in either family is overly attached to their surname. (E.g. I am attached to my family name so had to become a bdouble-barrel when I got married, as there was no way that I was letting go of the name that I grew up with.) If both you and your partner have brothers/sisters/cousins that can "carry-on" your family names, then there shouldn't be any issues with both of you changing yours.

I think it's a great idea. We toyed with it, but the combinations were just ghastly. If you can do it, and it's nice, then why not?

I think it's a great idea if you're both happy to do it, I say go for it

Interesting idea - with your names I like Jenson
