All four grandparents were born in different parts of Denmark and somehow I ended up in California loving country blues and bluegrass and other folk-related musics, but mostly the two first-mentioned.
I do like some of the Scandinavian fiddle music I've heard, but I haven't had much opportunity to hear a lot of it. I lived in Denmark from '72 to '76 and played and heard a lot of groups. At the time there weren't too many youn Danes playing their own folk music, but they played a lot of British Isles and Amderican music. One exception was a group called "Stegt Kartoffler og ...(forgot the last word)..." They played lots of old Danish dance music.
In terms of real ethnicity, though, I appreciate Spider John's album title;
Raised by Humans.
