She was also the aunt of Prince Georg Friedrich of Prussia, the current head of the House of Hohenzollern’s former imperial branch.
A life dedicated to children and music

Those engagements included visits to schools, social institutions, retirement homes and hospices. Marie-Cécile spent much of her life in East Holstein, in the northern German state of Schleswig-Holstein.

Her connection to Queen Victoria and the Romanovs
Marie-Cécile was born on May 28, 1942, in Cadinen, East Prussia. She was the eldest daughter of Prince Louis Ferdinand of Prussia and Grand Duchess Kira Kirillovna of Russia.
Her father was a grandson of Wilhelm II and later became head of the former imperial family. Following his death in 1994, his grandson, Prince Georg Friedrich, succeeded him.

Her maternal ancestry also connected her to Queen Victoria through the British monarch’s son, Prince Alfred, Duke of Saxe-Coburg and Gotha.
A royal wedding in Berlin and three children
In December 1965, Marie-Cécile married Duke Friedrich August of Oldenburg in Berlin. Their civil ceremony took place on December 3, followed by a religious wedding the next day.
The celebrations attracted considerable attention as the first Hohenzollern wedding in Berlin since 1913. A reception followed at Charlottenburg Palace, with the city’s then-governing mayor, Willy Brandt, among the guests.

In remembering Marie-Cécile, the House of Hohenzollern highlighted a legacy that extended beyond her royal ancestry. Years spent supporting children, encouraging young performers and helping more people experience live music.
