Feb. 26, 1933 Gmunden an der Traun Upper Austria (Oberösterreich), Austria
Danish royality. Youngest daughter of Christian IX of Denmark and Louise of Hesse-Kassel.
In her youth, Thyra had fallen in love with Vilhelm Frimann Marcher, a Lieutenant in the Cavalry, which resulted in a pregnancy. Her brother George I of Greece suggested that she have the baby in Athens to avoid scandal; the Danish press was told Thyra had been taken ill with jaundice. She gave birth to a girl, Maria (1871-1964), who was adopted by Rasmus and Anne Marie Jřrgensen of Odense shortly after birth and renamed Kate. Marcher killed himself on 4 January 1872 after a confrontation with the King. Thyra never saw her daughter again.
In 1878 she married Ernest Augustus, the exiled heir to the Kingdom of Hanover. As the Kingdom of Hanover had been annexed by Prussia in 1866, she spent most of her life in exile with her husband in Austria.
