My Four Bears migrated south to Northumberland and became Geordies.
One went to Australia and became quite well-off as a sheep farmer.

I think both the displaced Scots and the Irish famine survivors were extremely tough and resourceful people. They migrated, taking their culture all over the world and succeeded under awful circumstances.
(I'm rather proud, as I'm a mixture of Scottish and Irish blood!)

But one can't forget that many thousands died from starvation and want due to the indifference and cruelty of the rich and greedy.
