She was the youngest daughter of the Truchsess (seneschal) of Lithuania Johann Heinrich von Altenbockum by his wife, Konstancja Tekla Branicka, who had emigrated from Westphalia.
In 1695, fifteen-year-old Ursula married the Polish Kronoberkaemmerer Prince Jerzy Dominik Lubomirski. At that time, the Lubomirski family ranked among Poland"s most influential princely families. They maintained relations with Primate-Cardinal Michał Stefan Radziejowski, archbishop of Gniezno, who, after the death of the Polish king John III Sobieski, was chosen by the new king as his representative.
Nevertheless, the Pope soon took the highly unusual step of dissolving this "lucky little marriage".
In 1700 she became Augustus"s official mistress (Mätresse), replacing Countess Maximiliane Hiserle of Chodau, known to history as Countess Esterle. Augustus the Strong sent Ursula to Saxony and presented her to the Dresden court.
The courtiers were impressed by the beautiful, charming and high-spirited princess. On 21 August 1704 she gave birth a son, Johann Georg, later the Chevalier de Saxe, who was named for the king-elector"s father.
Only five days after her son"s birth, on 26 August 1704, Ursula was created Reichsfürstin (“Princess of the Empire” or “Imperial Princess”) of Teschen by Emperor Leopold I. This title was only honorific, because only national Princes had seats and votes in the Reichstag.
However, later that year, Ursula"s relationship with the King ended. In 1705, the Countess Anna Constantia of Hoym, later Countess of Cosel, replaced her as official mistress. Humiliated by the King and outlawed from the Dresden Hof (court), Ursula retired to a countryseat in Hoyerswerda.
Augustus the Strong loaned her 250,000 Imperial talers (Reichstaler) for the land, and later he gave her the complete property rights.
Then, Ursula moved to her Silesian residence in Breslau. Years later, after the King had banished the Countess of Cosel, Ursula returned to Dresden, where she occupied a respected position in the Hof.
The fall of Augustus II"s Lord Chancellor and Lord Chamberlain (Großkanzler) Wolf Dietrich von Beichlingen was at that time attributed to her. On 19 September 1734, after twelve years of marriage, Frederick Louis was killed during the Battle of Guastalla.
When the King-Elector died in 1733, Ursula was banished from the Hof.
Ursula died in Dresden, aged 62.
