I have no evidence to suggest that it was except maybe the size of the population. Is it possible that all changed utterly post famine, especially for those who survived and stayed in terms of how conservative a society we became? I would imagine joining religious orders became a much more viable career option as very few if any of them (the Catholic ones) died during the famine! Also we would hardly have had the rate of unmarried for a life time adults which we eventually did, highest in the world at one stage! And of course the Magdelyne concentration camps had yet to come into their own!
I throw it open to the house?
