It also fits all your criteria--except for the geography.
"From the Canebrake" by Samuel Gardner is a fun tune as well - Heifetz recorded it. https://www.youtube.com/watch?v=c1KshjWRRpE
For Scandinavian stuff, look into compositions by Ole Bull.
Vieuxtemps collection "Bouquet Americain" is a nice selection of folk tunes he arranged for his American tour. Maud Powell recorded "St. Patrick's Day" https://www.youtube.com/watch?v=XiwLw7cwWfc

Very tangentially, the Zwillich Fantasy for solo violin has some blues-y riffs that most violinists don't milk especially well.
On the subject of blues, there is, of course, the Ravel sonata.

And I am convinced that Ravel's admirer and would-be student George Gershwin alluded to that when he wrote "Summertime" a few years afterward. There is a Heifetz transcription, naturally.
Finally, for now, while the folk influence is more imagined than real, being played by an actual Hungarian brings out all kinds of things in this one that are no longer immediately obvious in the score:

"The second Sonata for Violin and Piano by Charles Ives is largely based in American fiddling idiom... particularly the second moment, and it's a lot of fun to play."

I thought of the same sonata. My violin instructor at Southern Oregon University played this sonata during the late 60's, and it was just excellent. I don't have a recording of it, yet I still remember how Ives so effectively wove Oh Suzanna and other folk songs into the music.
