My family roots on both sides are fairly well researched but undistinguished. Perhaps the best story I have to offer is of a thrice great aunt of the Guinness brewing clan who was disinherited for marrying into my Irish side of the family and converting to Catholicism.
I was talking to my Grandmother, Mothers side, one time on how my Grandfather didn’t look Irish, more like a Scot.
She said don’t tell anyone his family converted.
So years later I saw one of his family name shaking in his boots about a Protestant Minister of his family name preaching in Belfast, we are all going to die.
