There are lots of stories of religious persecution and cruelty in Ireland's history. During Henry VIII's rule all "Popery" was ruthlessly suppressed. According to one account, Theobald (de Burgo or Burke), a Dominican Friar and a group of like-minded catholics went to Dublin to 'maintain the Popes' supremacy'. All were horrifically tortured and put to death. ( some of these might make an appearance later..)
Theobald himself had his heart torn from his still living body.
And here he is(-- sorry it's late , I cant think of anything more to say about him right now...)
