"Maria Eleonora of Brandenburg (11 November 1599 – 28 March 1655) was a German princess and queen consort of Sweden.
She was the daughter of John Sigismund, Elector of Brandenburg, and Anna, Duchess of Prussia, daughter of Albert Frederick, Duke of Prussia.
In the year 1620, Maria Eleonora married the Swedish king Gustavus Adolphus with her mother´s consent, but against the will of her brother George William, Elector of Brandenburg, who had just succeeded her father. She bore her husband a daughter, Christina, in 1626.
She was described as the most beautiful queen in Europe, and, as her daughter later said, had ´all the virtues and vices´ associated with her gender.[citation needed]" - (en.wikipedia.org 12.01.2020)
