Friederike Elisabeth of Saxe-Eisenach

Fredericka Elisabeth of Saxe-Eisenach (5 May 1669 – 12 November 1730), was a German noblewoman member of the House of Wettin and by marriage Duchess of Saxe-Weissenfels. Born in Altenkirchen, she was the seventh of eight children born from the marriage of John George I, Duke of Saxe-Eisenach and Johannetta, Countess of Sayn-Wittgenstein-Sayn-Altenkirchen. From her seven older and younger siblings four survive adulthood: Eleonore Erdmuthe Luise (by her two marriages Margravine of Brandenburg-Ansbach and Electress of Saxony), Frederick August, Hereditary Prince of Saxe-Eisenach, John George II, Duke of Saxe-Eisenach and John William, Duke of Saxe-Eisenach. Life The already good relations between the Albertine and Ernestine branches of the House of Wettin were reinforced already in 1686 when Duke John George II of Saxe-Eisenach (from the Ernestine branch) arranged the marriage of his older sister, the Dowager Margravine of Brandenburg-Ansbach with John George IV, Elector of Saxony (from the Albertine branch). However, the union was a complete failure and ended childless. Both spouses died in 1694 and 1696, respectively. With John George IV's brother and successor, Frederick August I already married, Duke John George II had to search another marriage to bond again both Wettin branches.
