I’ve seen lots of people doing this mistake and I’m so done with it so let me correct this..
Stop calling Ragnar’s sons as “Ubbe Lothbrok” or “Hvitserk Lothbrok”. Lothbrok is a “nickname” for Ragnar, not a surname. His sons’ “surnames” are Ragnarsson until they get their own nickname. Björn’s nickname is Ironside because no axe or spear touched him in the first battle and Sigurd’s Snake-In-The-Eye because he basically had a snake in his eye.
I’ve also seen Lagertha’s name written with Lothbrok and it’s also a mistake. She doesn’t have a special name with her first name, so the last name is *her mom’s name*sdottir
↳ “ Who knows, Ragnar, what the gods have in store for us. But this, I can never imagine. If you have gone to Heaven, then we will never meet again. And yet, I think Odin will ride like the wind, and rescue you, and take you to Valhalla, where you belong, my own sweet Ragnar. And there, there we shall meet again, and fight and drink and love one another. For I have never stopped loving you. Not for one moment. You and I were born to be together.”
