I think it's your choice and your FH should be able to get over it if you'd like to keep your last name. As an illustrator, my name is my brand so I'll be keeping my last name, I don't really want to have to start over! Anyways, FI is from Cuba and in his culture, the women don't take on their husbands names so it works out. Everyone there gets two last names, the father's and then the mother's in that order. So following that, our kids would be first name - husband's first last name, my last name. Not sure if we'll follow that since my asian name sounds kind of stupid tacked onto his cuban one, so they'll probably just take his.
