Anyone know what the "Red House" title signifies?

The other old titles for it are "Where will bonnie Annie lie?" or "Where will our goodman lie?" - all from the 1690s, I think. "Bonnie Annie" or "Bonny Anne" seems to have been the most prevalent, and that's the title of Angus Mackay's pipe march version of the 1820s, at which point the tune seems to have stopped evolving new variants.
