Bernadotte lost his succession rights to the Swedish throne and renounced his titles in 1946 when he married the journalist Elin Kerstin Margaretha Wijkmark, daughter of Henning Wijkmark and wife Elin Larsson in New York City on 19 February. As his unconstitutional marriage to Wijkmark - enskild mans dotter - could not be approved by the Swedish government, Bernadotte knew he was giving up his Swedish titles and succession rights. They adopted two children:
Monica Kristina Margaretha Bernadotte. Married on 16 January 1976 and divorced in 1997 Count Johan Peder Bonde af Björnö. They have three children.
Christian Carl Henning Bernadotte. Married on 13 September 1980 Marianne Jenny, daughter of Jacques Jenny and wife Caroline Yvonne Venter. They have three children.
The Bernadottes lived for some time in New York City, where he worked as the representative of the Anglo-Nordic Trading Company. They made friends with the film starGreta Garbo, who stayed with them in their Swedish home near Båstad. On 29 September 1988, the widowed Bernadotte married Countess Gunnila Märtha Louise Bussler in Copenhagen and also became the stepfather of her three children from her previous marriage.
