I once had a chat with Barry over the phone where we were talking about the Siege of Derry and the subject of the unfortunate Robert Lundy came up, Barry was wondering if his actions are still remembered. They certainly still are;

It would still be current amongst Ulster Protestants, as a serious insult, to call someone a "Lundy" if they were thought to be betraying their fellows. The Williamite War still casts a long shadow.
