I am in need of the order in which the following characters died in the final battle. I can't see to find an exact order anywhere. If anyone has read something on this, please let me know.

This is who I need and the order I think they died in:

Fred
Remus
Tonks
Snape

Does that order seem right? I know of those four, Snape was definatly last because Harry saw their bodies on his way to Dumbledore's office with Snape's memories.

I am thinking Fred died first because the battle had only just begun.

Remus was seen battling with Dolohov before Tonks entered the battle.

So am I safe in assuming this is the correct order?

Thanks for your help.
