So in the book I’m reading now the author mentions that the Thirty-Year’s War was so destructive it ended folklore in certain areas. There are references to towns being unable to remember how things were “before the Swedes came”. Which is why most German fairy tales and medieval stereotypes come from southern regions and not Prussia which gives us a lot of modern German stereotypes etc.
I’m going to assume Davos Seaworth chose his name because of Davos Baratheon. I really like the idea of tiny child Davos thinking the Baratheons are really badass and picking a name from their family because of it. Then adult Davos gets knighted, serves for, and becomes a trusted advisor for the current Baratheon family.
