Princess Stephanie of Windisch-Graetz

As a child she suffered greatly from her mother's frequent absences, and her parents' inharmonious marriage. The couple was separated in 1924 and divorced in 1948. Her mother came to live in Brussels with the four children and Princess Clementine of Belgium offered a friendly refuge to Stéphanie.

In 1921, Archduchess Elisabeth had begun a relationship with the Austrian socialist member of parliament Leopold Petznek, whom she eventually married in 1948. Stéphanie got along well with her stepfather, but her relationship with her mother was not very good, and worsened after her second marriage. Archduchess Elisabeth did not like Karl-Axel Björklund, and forbade him to be in her house. Stéphanie financially supported her father Otto Weriand in later life.

Stéphanie had three elder brothers:

• Prince Franz Joseph zu Windisch-Grätz (1904 in Prague – 1981 in Nairobi), married to Ghislaine d'Arschot Schoonhoven (1912–1997) and father of
  • Princess Stéphanie Windisch-Graetz (1939–2019) became an artist, known for her photographic portraits using only candles as a source of light and for her sensual images from the animal world. She married Dermot Blundell-Hollinshead-Blundell (1935–2009) (a descendant of Nicholas Blundell). They are the parents of:
    • Henry Victor William Blundell-Hollinshead-Blundell (born 1967) and
    • Alexander Otto Blundell-Hollinshead-Blundell (born 1969), whose surname was changed to "de Windisch-Graetz" in Belgium in 2011.
  • Prince Guillaume Franz Josef Maria Windisch-Graetz (born 1950; unmarried).
• Prince Ernst zu Windisch-Grätz (1905–1952)
• Prince Rudolf zu Windisch-Grätz (1907–1939)

In 1933, Stéphanie married Count Pierre d'Alcantara de Querrieu (2 November 1907 – 14 October 1944). Count d'Alcantara was the son of Jean d'Alcantara de Querrieu and Baroness Marie-Lucie t'Kint de Roodenbeeke. Count d'Alcantara was a member of the household of King Leopold III. In 1942 he was arrested by the Gestapo and died two years later in the Sachsenhausen concentration camp. She had one child by her first husband:

• Count Alvar Etienne d'Alcantara de Querrieu (30 July 1935 – 5 August 2019)

In 1945, after the death of her husband, she married Karl-Axel Björklund (1906–1986). She had one child by her second husband:

• Bjorn-Axel Björklund (20 October 1944 – 7 September 1995)

During her long life, Stéphanie traveled extensively, especially in Africa, where her brother François-Joseph lived in Kenya, and also in South America, particularly in Argentina.
