Hi Georgina,
Josefs last name was Persson in the Swedish death index 1947-2003.
Josef was born 15 June 1889 in Gladsax, Kristianstads County, Skåne. He died 26 March 1955 in Malmö Sankt Pauli, Malmöhus Township, Malmöhus County, Skåne. He became a widower 17 February 1951. He was most likely married 21 July 1918, to Ellen Kristina, maiden name Jonasson, born 22 April 1893 in Simris, Kristianstads County, Skåne.
Josef also had a sister called Sofia. Sofia was born 22 October 1884 in Gladsax. Her maiden name is stated as Larsson in the Swedish death index 1947-2003.
Sofia married Anders Martinsson 20 December 1907. Anders was also born 12 September 1882.
Sofia died 7 March 1957 in Gladsax, Simrishamns Township, Kristianstads County, Skåne. Her husband died 4 June 1953.
What you can do to find out if Josef and Sofia had children or not is to order a copy of their estate inventories from the Regional Archives in Lund, where their children (if any) will be mentioned. You'll find the email address to the Regional Archives in Lund here:
