My mum didn't change her name when she was married, and all of us three kids were given her surname as our only middle name - not hyphenated or anything. Its a nice link for siblings. People sometimes question it as a strange "middle name", but as soon as I explain why its there, they think its great.

My husband and I have different surnames but we have chosen for our kids to have DH's surname as I have a poor relationship with my Dad and wouldn't want to carry on that name with my kids (despite still having that name myself..)

I have a friend who's kids have the mum's surname because the fathers surname was a shocker in terms of being teased at school etc.

And I have another friend who made up a surname based on the two surnames of her and her husband - thus creating a whole new one.

So many options!
