I think that when you want to find something more you look for why a writer shifted an idea. That gives you a clue to what they needed from that moment. There was an early draft of The Hobbit whereby names and characters were different. Smaug was called something else, for example. He was known as Pryftan. I think at one point, Thorin was called Gandalf. And of course, Gandalf means “Elf of the Wand.” It’s kind of weird for Thorin. So he’d obviously deliberately changed the name because he wanted that name to represent something, as all the names do. And the translation of Thorin is “Darer” (Old Norse) So Thorin is the one that would dare to reclaim the kingdom.
