Not bad at all, for the first quiz! - Few notes:You forgot Isildur. And Celeborn wasn't a Elf Ring owner, Gandalf had the Third one. You could accept Gil-galad, Cirdan, or Celebrimbor as the previous owners, if you want. And yes, I'm a nerd. 🤓
firstly, owners of the ring: 1st Sauron, 2nd isildur, 3rd deagol, 4th smeagol, 5th gollum (yes they are different people) 6th bilbo 7th frodo, 8th sam. as for the elven rings, their respective owners (at the time of the war of the ring) elrond, galadriel and gandalf (whos ring was given to him by cirdan the shipwright)
I'm not sure...
If you could find a website, that would be great.
(I'm just working on memory) ;-)
