Björn has a sister I think but Idk about the others. In 1977, the German teen magazine Bravo published a poster and a complete biography with details of Frida's background, including the names of her father and mother. It was seen by Frida's German half-brother, who went to his father Alfred Haase and asked him if he had been in Ballangen during the war. A few months later, Frida met Haase in Stockholm for the first time.
