メクレンブルク家
She was born in Kiel in the state of Schleswig-Holstein the eldest daughter of Duke Christian Louis of Mecklenburg-Schwerin and his wife Princess Barbara of Prussia (1920-1994). Her father was the younger brother to the last surviving male of the House of Mecklenburg-Schwerin, Friedrich Franz, Hereditary Grand Duke of Mecklenburg-Schwerin. As Donata had only one sister Edwina (born 25 September 1960), and as her uncle had no children the House of Mecklenburg-Schwerin became extinct in the male line in 2001 when her uncle died. As a result, the Mecklenburg-Strelitz line, headed by Borwin, Duke of Mecklenburg, will become the only surviving line of the House of Mecklenburg when both Donata and Edwina are dead.
