We've got a name! Originally I had planned on a different surname for Reynir, because I was afraid a lot of people would think that Árni was his father rather than great grandfather if his last name was just bluntly Árnason. But then I realized that most people don't even know how Icelandic last names work to begin with and I should just be happy if people make the familiar connection at all. So Reynir Árnason it is, great grandson of Árni Reynisson. x3
