I am assuming the photo of Alma and Gösta was taken in 1911 and the picture of Paul and Torborg was probably taken around 1912, given the ages of the children. The photo came form an exhibition that i couldn't quite remember the name of.
The photos of the Palsson family above can also me viewed on Youtube, under the title of TITANIC GHOSTS DOCUMENTARY. pLace that in to the search engine and a 4-part video will appear. For anyone interested in the Unknown child, i'd advise you watch the video.
Make note: The Panula photos at the end if part 4, is not the family. It was a mistaken identity.
