This photo was mis-identified for several years, but it is currently believed to be a photo of Johanes Olson. Unfortunately I have been unable to identify the children, or the date – either would pin down the other. The holder is marked “Aulin Studio”, but I have been unable to locate any information about the photographer.
I have Great-Grandpa Olson’s bible on my shelf. On its front end paper it includes a genealogy by his father, Peder Johanesen Moen, which states Johanes’s birthday as 2 February 1843.
