In our household there are three different surnames.

I don't think the name matters too much to be honest. I've thought about changing my boys names to at least the same as mine but I never have. It wouldn't cost much to do.

Anyway, some fathers are arseholes and don't do what they're supposed to do. Maybe he'll come back one day and want to spend time with them and maybe not. It's important for the kids to know that the part of their heritage from their father is not something to be ashamed of because it's part of them too. I'd say let them keep their name. One day when they're ready to make their way in the world, they'll be able to make their own decision about it.
