This is similar to what they used to do, bit with children's last names. So if your father's name was Grace, your last name would be Grayson. If your father's name was Peter, your last name would be Petersdotter. It makes it very difficult to keep track of family members.
I beber understood why you do that in America. Im From spain And here we get The fiesta surname Of our father and the first one of our mom. So we have 2 surnames. And it's been like since since for ever. Same in other countries from Europe and the world.
