Queen Christina of Sweden raised her illegitimate half-brother to the dignity of a count when she gave him the Countship of Nystad in 1647.
In 1679, following the Treaty of Nijmegen, Sweden pawned Wildeshausen's overlordship to the Prince-Bishop of Münster in exchange for a loan of 100,000 Riksdaler.
His remaining sister and the last official bearer of their surname, countess Henrietta Polyxena (1696-1777) died in 1777.
These descendants were daughter Catharina Sophia (1717–64), who married the baron Eric Sparre (1700–42), Lord of Forbach in Lorraine; and son Count Henning Gustav (1719-1787).
He married baroness Luise von Esebeck (born in 1746), daughter of Johann Asmus Freiherr von Esebeck, and had children who continued the Vasaborg name, the male line of which died out in 1872 and the female line of which still exists.
