Anna Margareta von Haugwitz (16 January 1622 in Calbe (Saale) – 20 March 1673 in Stockholm), was a German noblewoman, a daughter of Baltzar Joachim von Haugwitz and his wife, Sophie von Weltheim.[1] Soon after her birth, both parents died.
As an orphaned ward of the German Countess Elisabeth Juliane of Erbach (who married the Swedish commander Johan Banér in 1636), she met Carl Gustaf Wrangel in the Swedish military camp. They married out of love in 1640, which was controversial – he was a member of the most powerful Swedish nobility and his family disproved because she was of the untitled and poor nobility.
The relationship was a happy one. After the Thirty Years' War, they lived mainly at the Wrangel estates in Swedish Pomerania, where she died. She bequeathed a sum of money to her hometown Calbe, to be paid in annual installments on her birthdays.
