I thought that they 'volunteered' to be relocated, due to harsh conditions and short nunbers of people fit enough to gather food.
Big up to religion, really long sermons during prime food gathering time, cracking plan. (*My dad actually saw a church revolt – lates 50s North tip Scotland, cracking Sunday, after 3 hours this young bloke got up and apologised and said this is the first fishing day for 4 days and my family haven't eaten for 3 – I'm getting them food – half the church left)
They didn't do well on relocation either, having no immunity to common mainland diseases wasn't that helpful.
Mind you the marriage test might help – stand on a slab – toes over the edge, with a vertical drop to the sea and touch your toes……
