I, Del, asked :
"Another question : why is the motto stated in French to start with ?
Black is not, even remotely, a French name, so why use French ?"

Nora answered :
"Because French is the historical language of the English aristocracy,
 and having a motto like that points out both their age and their 
upper-class status.  Remember that the motto of the royal family is
'Dieu et Mon Droit', after all."

Del replies :
Really ? I didn't know that. So technically, I couldn't *remember* it :-) 

You *do* realise, of course, that you've just made a direct connection
between the Black family and the classic, *Muggle* aristocracy ?
Smells of HBP. Or does it ?
