I'm delighted to hear from you, and would like very much to exchange information. So far, I have Jonas (Johannes) Jonasen, born about 1785 in Hurdal, and married to Mari Johannesdatter. I have 5 children listed: Johanes - born 29 Jan 1819, married 13 Apr 1849 to Karen Margrete Olsdatter, and died 21 Mar 1895; #2 - Anders - born 9 Nov 1821, died 12 Sep 1822; #3 - Anders - born 3 Aug 1824; #4 - Erick - born 31 Oct 1826, married Inge Cecelia Olson on 16 Dec 1858, and died 12 Aug 1915 in Harvey, Wells County, North Dakota; and #5 - Kirstine - born 12 Jan 1829, married 20 Feb 1851 to Halvor Pedersen (from Gran, Oppland), and died 5 Jan 1916 in Twin Valley, Norman County, Minnesota (my great-grandmother).
Does the above information agree with yours? I have quite a lot of research done on Kirstine and Erick. I hope you have info you can send to me. Why don't you contact me via my email address, and we can continue communicating that firstname.lastname@example.org
