Besides the obvious Finrod Felagund, and later Thingol, the list has to contain Dior Thingols Heir - and probably also Orodreth who ruled Nargothrond, though he is reffered to as "lord of Nargothrond" and not king ...
This is actually an interesting question... because it (to me) raises other questions...
What happend to the Nauglamir? Was the Silmaril ever seperated from the Nauglamír? Could we count Eärendil to the list above? He was lord of the people that survived the fall of Gondolin and the Sack of Doriath, and he chose to be counted among the elves... But I can find no reference to the Nauglamir at the Mouth of Sirion or being with Eärendil later - It is said that he bore the Silmaril on his brow - The Nauglamír is not a thing one would wear on ones brow is it? So maybe the Nauglamír never left Doriath - only the Silmaril?
These were my thoughts
