Norwegian Olsens

I'd like to find some Norwegian Olsen cousins during a visit I plan there in August. "No problem finding Olsens in Norway," you say? Well, finding the right ones may not be so easy, what with privacy regulations and all. Per my previous research (including significant help from this website -- thank you!) here's my gg grandfather's family: Descendants of Ole Karl Jonsen 1 Ole Karl Jonsen b: 1811 Nordalens Præstgjeld, Norway d: Unknown .. +Gurine Rasmusdtr b: 1823 Nordalens Præstgjeld, Norway d: Unknown ...2 Inger Regine Olsdtr b: 19 Sep 1847 Nordalens Præstgjeld, Norway d: Unknown ...2 Johan Olsen b: 06 Oct 1848 Nordalens Præstgjeld, Norway d: 13 Nov 1920 Portland, OR e: 18 Mar 1874 Allan Line, from Bergen ....... +Oline Christiansdtr b: 26 Oct 1847 Engeset Farm, Nordalen, Norway m: Abt. 1880 US? d: 16 Mar 1942 Clackamas Cty, OR e: 10 May 1879 From Bergen, Stjerne Linien ...2 Else Olsdtr b: 12 Dec 1850 Nordalens Præstgjeld, Norway d: Unknown e: 1888 Status of "gardmanndtr" (farm-owner's daughter?) ...2 Tomas Olsen b: 03 Jun 1853 Norddalen, Norway d: Unknown e: 02 Nov 1888 (Second?)

All this is in Møre og Romsdal. Four children emigrated (Johan (my g grandfather), Else, Tomas (twice?) and Jens (one of twins)). One died as an infant (Ole). But three sisters I'm still tracking (Inger Regine, Nicoline Birgitte, and Elen Malene (the other twin)). Might they have stayed in Norway and started families of their own? If I could track down contemporary descendents of these sisters that would be ideal. If I hit the jackpot, some one in that branch of the family is also a genealogy enthusiast. I'm going to compose another query like this one, with details about my gg grandmother's siblings, which I'll also post to this most-helpful forum. As before, research suggestions are most welcome.
