Lyngstad believed that her father, Alfred Haase, had died during the war on his way back to Germany as his ship was reported to have been sunk. However, in 1977, the German teen magazine "Bravo" published a poster and a complete biography with details of Lyngstad's background, including the names of her mother and father. It was seen by Lyngstad's half-brother, Peter Haase, who went to his father and asked him if he had been in Ballangen during the war. A few months later, Lyngstad met Haase in Stockholm for the first time.
