I don't recommend using the Grey Company site however, the Elvish on that site is commonly known as Grelvish and is very innaccurate. It's

Encylopedia of ArdaThat site will also provide accurate information on all divisions of Elves, and their history. It is very useful.

There are the main Elven divisions and how each division came to be.
