Enunciated in 1907, Ne Temere requires that all children of a mixed marriage be brought up as Catholics. Before 1907 the tradition was that the boys in such a marriage would be brought up in the father’s faith and the girls in that of their mother.
Ne Temerre resulted in couples of both faiths being rejected by their families, particularly farming families, where the oldest boys who married a catholic would result in the Catholic children of that family inheriting the land. But the impact of Ne Temerre had much, much wider repercussions than this and its a subject that requires greater study. I would recommend “Different and the same” by Deirdre Nuttall.
Ne Temerre to all intents and purposes was a cleansing of Protestants from the Republic of Ireland.
“Under the stone eyes of Mary” is the title of a novel I am currently editing.
Being second generation Irish was confusing on many levels, returning “Home” raised further confusions.
Having a Catholic grandfather excluded by his farming family, and a Protestant grandmother excluded by her family provided a minefield when returning “Home”.
