Yes, I have, all 8 of them. And by the way my name is Sindarin/Quenya. Good Lotr Youtube channels are Men of the West. And The History of Middle Earth. Your Welcome.
Hey, I'm also subbed to Men of the West!!! And what does your name mean? I don't recognize any Elvish (Sindarin or Quenya) elements in it. I guess I could just look it up in the Etymologies, but I'm too lazy for that right now lol.
You won't find my name that easliy. Eryn in Sindarin means woods. Cesicil in Quenya means dagger. The others I would like to keep secret, unless you look them up in th etymologies yourself.
I was using the Etymologies in The Lost Road and The Silmarillion. I couldn't find anything for Grythyl, so I tried setting Google Translate to Welsh (the language Sindarin is based off of), ran it through, and voilà, "crystalline"!
