The Irish were decedents of Abraham who had traveled to Egypt, and then fled egypt, eventually arriving in spain, france, and then settling in Ireland. it is unknown whether they descended from judah or one of the other tribes. If memory serves, King Tut? was a grandson of Joseph, and the daughter? of Tut was Scota. Scota founded Scotland after she left Egypt and her traveling party/family settled in Ireland. Or, generally, this is what happened. It should also be noted that the tribe of judah were originally called jews, but they conquered the edomites and forced them to become judeans. After this, the edomites became known as jews as well. Christ came to save the lost tribe of israel (the jews), leaving the edomites to rule judea. later, those edomites (who call themselves 'jews' to this day) conquered the khazars, and now the 'jews' of today consist of edomites and khazars, and have no blood relation to judah (though they do have a blood relation to abraham through esau, though this is not sufficient to stop them from sacrificing and eating babies like their Canaanite ancestors on their mother's side)
