Sibylla Calma Marie Alice Bathildis Feodora was the daughter of Duke Karl Edvard of Sachsen-Coburg-Gotha and Princess Viktoria Adelheid of Schleswig-Holstein-Sonderburg-Glücksburg. She grew up in Coburg and had four siblings.
The Royal couple settled at Haga on Northern Djurgården, just outside Stockholm. Princess Sibylla gave birth to five children: The Princesses Margaretha (1934), Birgitta (1937), Désirée (1938), Christina (1943) and Prince Carl Gustaf (1946).
Life for the family changed instantly when Prince Gustaf Adolf died in an airplane accident at Kastrup airport (Denmark) on January 26th,1947. In a rare interview Princess Sibylla told journalist Margit Vinberg from the weekly Veckojournalen that it felt as if “the floor fell out from under my feet.
The family moved to an apartment at The Royal Palace in 1950. Princess Sibylla fulfilled her official duties with joy and dignity. Many remember her natural royal style at events like the Nobel Festivities and the formal opening of the Riksdag (Sweden´s parliament).
In private she lived for, and through, her children. Some of the highlights of her life included her son´s graduation and the weddings of her four daughters. She became a loving grandmother to many grandchildren.
Despite strong media interest in Sibylla´s daughters (know as the Haga Princess´) and the cute little Prince, there were very few people outside the family that really knew the real Princess.
After the death of Queen Louise in 1965 Princess Sibylla became the first lady of the nation and took over many of The Queen's official duties.
Other hobbies included flowers, painting, embroidering and driving. If The Princess had been able to have a career she most likely would have worked with interior architecture. She found much pleasure in decorating her own home at Hagaberg, close to Solliden (the Royal Family´s summer home on Öland). She spent many summers there and loved it as much as her children.
On the passing of Princess Sibylla, journalist Barbro Alving wrote:
- There was warmth in Princess Sibylla´s being, a kind zealousness in her interest for people, which was greater than most people in the country believed.
Princess Sibylla died at The Royal Palace in Stockholm on November 27th, 1972. The funeral took place on December 7th at The Royal Chapel. She rests beside her husband at The Royal Cemetery at Haga Park.
Upon her death, Gustaf VI Adolf´s secretary Carl-Fredrik Palmstierna wrote:
- I always admired the tact at which Princess Sibylla handled the difficult position she had during the Second World War.
