There is no Gornuk.
Griphook almost died but didn't, and Dobby got stabbed by Bellatrix Lestrange as he was helping Luna, Mr. Ollivander, Griphook, Harry, Ron and Hermione escape, and that killed him.
Fred got killed by McNair (a Death Eater. I think it was McNair, don't quote me on that though.), and George lost an ear to Snape near the start.
Nobody knows how Remus, Tonks or Collin Creevey died.
Grawp, Hagrid's baby brother gets badly injured, but desn't die, same with Firenze and Roan the Centaurs.
In the first book, Professor Quirrel got killed by Voldemort, and in the fourth book, Cedric Diggory got killed by Voldemort also.
In the fifth book, Sirius Black, Harry's godfather gets killed by Bellatrix, and in the Sixth book, Dumbledore gets killed by Snape. Then in the seventh book, Voldemort uses his snake Nagini to kill Snape.
Then, of course, Harry makes Voldemort's killing curse rebound, because Harry is the true owner fo the wand Voldemort is using, the Elder Wand, and it can't kill it's true owner. So that kills Voldemort, which means that,really, Voldemort accidentally killed himself. Lol. Kinda funny when you put it that way. The most powerful dark wizard in a century accidentally kills himself.
I think that's it
