Helge:
Good to have you join! I'm not Norwegian, but my wife is; her dad was born near where you live. He was born in Kvitsoy and raised in Rennesoy, and emegrated to US as a teenager. We went to Norway a few years ago, but didn't have time to hunt up his birthplace; always planned on doing that when we retired.
Her dad also played the hardingfele (is that right?) or Hardanger Fiddle, and used to play folk songs from that area that he learned as a boy. Sure wish I had recorded some of them before he died!
Again, welcome abord!
