Fawkes & Rookwood

[Brian <bkb042@yahoo.com>]

This could be an interesting little parallel that I've found. 

It's generally accepted that Fawkes the phoenix is named after Guy 
Fawkes of Gunpowder Plot fame. While researching the plot, I found 
the name of one of his co-conspirators: Ambrose Rookwood. Is Ambrose 
the gr gr gr gr grandfather of Augustus (mentioned in GoF)? Did JKR 
use this surname knowingly? If so, what could it portend?
