Ole Karl Jonsen of Norddal

My research suggests that ggGrandfather, Ole Karl Jonsen, was born in 1811 in Nordalens Præstgjeld, Gjerde farm, Møre og Romsdal. But so far I cannot find when and where he died. He was married in 1846 to Gurine Rasmusdtr Lingaas, who was born in 1823 in Norddal and died after 1900 -- I would also like to find specifically when. By the time of the 1900 Census, she was living on Kavli (Grytten) as a føderådsenke, apparently with her daughter and son-in-law (see below). Up to 1855, Ole Karl Jonsen and his family lived on Gjerde farm, but then traded his interests in that property for Grønningsæter (also in Norddal), which he then sold off in pieces. I think Ole Karl's parents were Jon Jonsen Gjerde (b. 1780 and d. 1844, both in Norddal) and Torine Ellingdtr Heggen (b. 1783, m. 1807 and d. 1866 -- all in Norddal I think). Ole Karl and Gurine had eight children, seven of whom survived. With help from others on this forum, research suggests six of these seven survivors emigrated, including my gGrandfather Johan Olsen. I think the only sibling to stay in Norway was Inger Regine Olsdtr (b. 19-Sep-1847 in Norddal, d. ?). Some time before 1886 she apparently married a Fredrik H. (full name unknown), listed as having been born in 1840 in Norddal Rom. They apparently had at least two children born in Norddal: Tomas Fredriksen (b. 1886) and Marie Fredriksdtr (b. 1890). If I could find any living descendents of Tomas or Marie, they would probably be my closest relatives still living in Norway. Any research hints would be most welcome. PS: We were in Norway last August and we found and photographed all these old family farmsteads. It was most satisfying to see the actual sites.
