I have a hard copy of a photo of Syver Guttormsen Gaarder and wife Barbo Helgesdatter Aasli (Gaarder) taken ca. 1849, probably about the time of their coming to America. According to the information on the back of the photo, Barbo was 15-1/2 years old when they married on 1 January 1827.
I'm not sure how they are related to me except that my great grandmother Bertha Oline Guthormson (Gaarder) married my great grandfather, Knut O. Gordon 26 December 1868, New Glarus, Wisconsin.
Let me know if our information connects. I'd be happy to share what I know.
