Looking for family in Norway

Hello all, I have been very successful finding ancestors, now it is time to find living members of my family tree.[:)] I'm looking for any decedents of John Olson Aasen born 1815 at Moen/Sem Nordre, Heddal, Norway and died in 1868 on Aasen, Heddal, Norway. He married Thore Olsdtr Soubøe born 1819 on Saubø/Tuddal, Hjartal, Norway she passed on 1861 presumably also on Aasen farm. They had five children: Gonne (1842), Ole (1844), John (1847 - my ancestor), Thore (1851). John Johnson Aasen married Ragnild Torstensen Aasen they had 11 children, 9 of them were born in Norway. All there children came with them and settled in Waupaca County, Wisconsin. If anyone knows what has happened to the John's brother and sisters or if they are decedents please let me know! I have a cousin planning a trip to Heddal region/parish and would love to meet some cousins if they are still living in the area. Thank you! Heidi
