Thankyou very much for saying that <3
There is no list, that I know of, and most names of Knights can probably be heard whenever Arthur speaks of them…but you’d have to look at all the episodes again I guess xD
We do know of a Sir Owain (there’s a tag!) though, who unfortunately died, bravely fighting Sir Tristan de Bois, Arthur’s dead uncle in S1 E9 :s
Also, I’m not sure this is a dead Knight, but an artist called I-Kay was an ‘extra’ Knight for some episodes in S4 (not sure about rest of series), and he tweeted a pic of the scene you can see him in:

I did ask him if his character had a name, and he replied:
(Sir Kay is quite an appropriate name, don’t you think? ;)
Hope this spam was informative xD
And if you find the list you’re looking for, please do let me know! :D
