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. She was close to her aunt, Olive, who once stated that she saw how lonely and subdued Anni-Frid was, and, consequently, always did her best to make Anni-Frid feel loved and welcomed, during her visits. During her childhood, Anni-Frid had close contact with her family, particularly her uncle and four aunts, at her birthplace during the summer holidays. Anni-Frid grew up in Torshälla and began to attend school in August 1952. In June 1949, they both relocated to Torshälla, outside Eskilstuna, where Anni worked as a seamstress. Synni died of kidney failure soon afterwards, aged 21 years, leaving Anni-Frid to be raised solely by her grandmother. Synni joined her mother and daughter in Sweden, and the three moved to Malmköping (72 km from Stockholm). Her grandmother took any available job while living there, whereas Synni remained in Norway and worked for a time in the south of the country. Anni-Frid was taken by Anni to Sweden, where they settled in the region of Härjedalen. In early 1947, Anni-Frid, her mother Synni, and her maternal grandmother, Arntine "Anni" Lyngstad, left their birthplace in Norway, fearing reprisals against those who had dealings with the Germans during the occupation. Haase had returned to Germany when his unit was evacuated.

Heinrich Ruzzo died of lymphoma in October 1999, leaving her the titles of Dowager Princess and Countess. In 1992, Lyngstad married Prince Heinrich Ruzzo of Reuss, Count of Plauen, who was a prince of the former sovereign House of Reuss since then she has held the titles of Princess Reuss and Countess of Plauen with the style of Her Serene Highness.

The couple separated in 1980 and divorced in 1981. The following year she was engaged to Swedish pianist Benny Andersson, also a member of ABBA, until they married in 1978. In April 1964, Anni-Frid married Ragnar Fredriksson, with whom she had two children they divorced in 1970.

In 1996, Lyngstad recorded her final album in Swedish, Djupa andetag ( Deep Breaths), released by Anderson Records, before retiring from music. After the break-up of ABBA, she continued an international solo singing career with mixed success, releasing the albums Something's Going On (1982) and Shine (1984) the latter being her last international album. Although she had moderate success in Sweden, as she was a contestant for Melodifestivalen 1969 with her song " Härlig är vår jord", she did not reach international fame until she joined ABBA, which has sold over 150 million albums and singles worldwide, making them one of the best-selling music acts in history.

She won the competition with her song, " En ledig dag", leading to a television appearance on Hylands Hörna on Dagen H as a result, she was signed by EMI, and in turn was signed by Stig Anderson's record label, Polar Music, after years of releasing several singles and an album, Frida under the earlier record label. Princess Anni-Frid Reuss, Dowager Countess of Plauen ( née Lyngstad born 15 November 1945), better known by her nickname Frida, is a Norwegian-Swedish singer, songwriter and environmentalist, who is best known as one of the founding members and lead singers of the Swedish pop band ABBA.īorn in Bjørkåsen ( Ballangen), Norway, to a Norwegian mother and a German father, she grew up in Torshälla, Sweden, and started her first solo career there, as a jazz singer in 1967, through a talent competition called New Faces.
