December 17, 1957
The Grand Ducal Court in Luxembourg "formally announced" the engagement of Princess Marie-Adelaide, daughter of the Grand Duchess of Luxembourg, to Silesian count Karl Josef Henckel von Donnersmarck.
The announcement did not include a date for the wedding, but "court sources" state that the marriage will take place in the spring of 1958 at Luxembourg's Cathedral.
Princess Marie Adelaide, 33, is the second of Grand Duchess Charlotte's four daughters, and the last to marry.
She is also the daughter of Prince Consort Felix, who was born a Prince of Bourbon-Parma.
