family left behind

I have located many of the family members and there descendants in North America. Now we going to Norway this summer with my nephew and are hoping to find surviving family members there. Unfortunately the people we visited in 2006 won't be available this time. I have some family names of recent family members in Stryn but. I am not sure how to get a hold of them Any ideas would b e welcome. There are also family members in Oslo but unfortuneately as up to date. Like about 1925 for the last. My great Gandmother was born on the Vespestad farm on Bomlo island. Any help would be greatly appreciated .
