"when Geordie stole 16 of the king's red deer and sold them in Bohemmy - does it mean Bohemia? and anyway is it Bohemmy or Bohenny?... "

It's usually Bohenny, which does mean Bohemia. I looked up a bit of stuff about Bohemia, and one of the things I noticed was that deer are so common there that they've become a pest, necessitating a cull. Not much hope for Geordie's business plan, then, even if he hadn't got hanged.
