If anyone's familiar with Tim Tzouliadis' 2008 book, 'The Forsaken', it's an account of the Americans who immigrated to Soviet Russia in the early 1930s and what became of them as they got swept up by Stalinism. It's certainly a part of history I had never heard of -- several thousand Americans, some communist true believers and others beleaguered coal miners and other down-on-their-luck souls seeking out the good life in the USSR.
It might be worthwhile to put together a project for them and connect them to their families. Maybe a tag?
