== Origin of the name Bilbo == 

 This is a query I have related to another article and maybe you, Tolkien enthusiasts, may help. 

 The name bilbo appears in classical English as a type of sword (see Bilbo (sword)), which is mentioned by Shakespeare's character Pistol in the Merry Wives of Windsor: 
 :Ha, thou mountain-foreigner! Sir John and Master mine, 
 :I combat challenge of this latten bilbo. 
 :Word of denial in thy labras here! 
 :Word of denial: froth and scum, thou liest!  
 and is ethymologically linked to the Basque city of Bilbao (also known as Bilbo by locals and Bilboa in old English) 

 My question is: does anybody know for sure (and can document somehow) if Tolkien's name choice for this character was inspired by these cultural references (sword, Shakespeare)? I feel it's probably the case but I'd like to have more definite information, thanks.
