Thanks yes I agree the more info available the better the chance of someone being able to help. The photo of the children on Flicker was posted by me, Oluf is a cousin and we have been in contact.
This is a photo of Jens Christian Clausen and Sophie Emilie Jurgens don't have a date for the photo but assume this is a wedding photo their wedding was on 17 April 1891
Sophie was born 15 Sept 1868, Dunsum, Fohr died 5 May 1905 Dunsum, Fohr
Jens was born 20 Dec 1866, Rantrum, Denmark died 5 Dec 1939, Oldsum,Fohr
I edited to add a photo of their five children
