characer limit prevented me from adding this, but while Hugh O'Neill and the others failed to return-their ancestors didn't.
During the Cromwellian invasion the sons or nephews/grandsons of many of the men who left in the Flight of the Earls returned home to fight. Owen Roe O'Neill is the best known; he was an extremely talented soldier (he served in the Spanish netherlands for a long time) and is also the first known instance of someone flying a Green Harp flag for Ireland; it was on the ship he arrived on in Ireland.
