Partly true. Many of my ancestors were noted ecclesiastics including the most Reverend Redmond O’ Gallagher (1521 - 1601), a bishop of Derry who was martyred for the aid he rendered to survivors of the Spanish Armada.
I totally agree with your interpretation of “Black Irish.” And as for the actors.... Matt Dillon, Kevin Dillon and even more representative of “Black Irish”... Peter Gallagher.
Thanks for your clarification and for pointing out that helping the Spanish was on pain of death, which explains why, even though there might have been widespread sympathy for them and cases of life-risking aid and hospitality, most were killed by the British establishment in Ireland and their Irish adherents.
