Both of those sound very interesting.
Slovenia is a beautiful country, and I’d love to visit one day. From pictures I’ve seen, it looks a lot like the Austrian or Italian Alps...but prices there are much lower. Supposedly a great vacation destination. Good trout fishing, too, apparently.
The best-known Slovenian-American may have been Louis Adamic, who died in 1951. He could write in an interesting way, but had strong left-wing sympathies and was a noisy backer of Tito during and after WWII. He died under mysterious circumstances, perhaps murdered by agents of Stalin because of his support for Tito. His The Native's Return has interesting sketches of Yugoslavia in the early 1930s.
