I question that statement. Of course the population has recovered -- they just live outside of Ireland. My great grandfather left 13 children when he died and countless descendants in subsequent years.
That is true. Thank God for the Irish diaspora: phenomenal music and red-headed girls
Well our population has recovered they just did it in the US.
The Welsh, Cornish, Scottish, Manx, Breton and Galician populations show a similar distribution ~ albeit without all that UK'ness.
Wasn't just the potato famine did that.
