In the 1950s, Sartorius had a professional bobsled career. He competed in the 1956 Winter Olympics in Cortina d'Ampezzo, finishing fourth in the two-man event and ninth in the four-man event.

He was the second child and son of Carlos Sartorius y Díaz de Mendoza (1898–1966) and his first wife, María de Lourdes Cabeza de Vaca y Carvajal (1903–1940). Through his father he was a great-grandson of Luis José Sartorius, 1st Count de San Luis, who was Prime Minister of Spain from 1853 to 1854, during the reign of Queen Isabella II. By his mother´s family side he was a first cousin of both the Marquess of Portago known as Alfonso de Portago and of the actor and writer Jose Luis de Villallonga y Cabeza de Vaca, 9th Marquess of Castellbell.

After the death of his elder brother, Antonio Sartorius y Cabeza de Vaca, 3rd Marquess of Mariño, on 24 December 1976, he succeeded as the 4th Marquess of Mariño.

Sartorius married first Isabel Zorraquín y de Corral (1940–2009) from Argentina on 24 April 1964 at the Basilica of Our Lady of the Pillar, Buenos Aires;^[2] they later divorced in 1974 (since the Marquess remarried in the Catholic Church in 1988, it should be supposed that his first marriage got a canonical annulment before that date). Together they had three children, two daughters and one son:

• Isabel Sartorius y Zorraquín (born in Madrid in 1965); after the divorce of her parents, when her mother remarried in 1978, she went to live with her in Lima, Peru. She later studied in Washington, DC. She had a relationship around 1989 to 1991 with Felipe, Prince of Asturias.^[3] Isabel says that the relationship ended because both were very young, and he adds that Queen Sofía was always very supportive.^[4] She later had a relationship with Javier de Soto y FitzJames-Stuart, a descendant of James II of England via his son, James FitzJames, with whom she had a daughter, Mencía de Soto y Sartorius, who was born on 25 July 1997 at Madrid, Spain.^[3]

In February 2012, Isabel published her memoirs, titled Por ti lo haría mil veces, which translated means For you I would do it a thousand times. In them she refers to her relationship with her mother through the times when her mother was addicted to cocaine.^[4]

• Cecilia Sartorius y Zorraquín (born 1967), who married on 30 June 1990 Federico Green from Argentina.^[5] They had three children: Marcos Bartolomé, Pablo Federico and Antonia.
• Luis José Sartorius y Zorraquín, 5th Marquess of Mariño (born 1970); became the new marquess upon his father's death in 2002. He has a relationship with Bárbara Pérez Manzarbeitia, and they have one son, Vicente (born 2011), and one daughter, Isabel (born 2012). They married on 22 June 2013.^[6]

Secondly in 1988, he married Princess Nora of Liechtenstein (born 1950) at St. Florin's in Vaduz. With the princess he had one daughter:

• María Teresa Sartorius y de Liechtenstein (born November 1992).
