I'm wondering (having only seen the movie once long ago)...the attack made on the garrison was for revenge for the killing of Wallace's beloved. Often used as an endearing term after particularly fine renditions of songs sung by women (usually from the men this comes) is...something that sounds like "maith cailin" which...if it is actually "maith" and not "mo" ...means "good girl"..and is a term offered quite respectfully.
Is there a connection of some sort here?
