What's in a name? - Weasleys

[ffimiles]

No: HPFGUIDX 36389

On the subject of the Weasley name, ir ead somewhere that there was a 
character called 'Running Weasel', who was a great stratagist and a 
great leader of men - ala Ron's Chess prowess - though he did 
ultimately fall in battle.  This was on some website about the names 
in HP - i.e that there is a figure in [I think] Greek mythology 
called Hagrid Rubeus.  
Just another theory about the name - or maybe JKR just liked the 
sound of it!  I do!
