Vem gifte sig med Marie Elisabeth of Brunswick-Wolfenbüttel?

Marie Elisabeth of Brunswick-Wolfenbüttel (7 January 1638 - 15 February 1687), was a German noblewoman of the House of Welf and by her two marriages Duchess of Saxe-Eisenach and Saxe-Coburg.

Born in Brunswick, she was the second of the three children of Augustus the Younger, Duke of Brunswick-Lüneburg and his third wife, Duchess Elisabeth Sophie of Mecklenburg. Marie Elisabeth and her older brother Ferdinand Albert are the only surviving children of their parents' marriage. In addition, they had seven older half-siblings from Duke Augustus' two previous marriages, of whom only four survive adulthood: Rudolph Augustus, Sibylle Ursula (by marriage Duchess of Holstein-Glücksburg), Clara Augusta (by marriage Duchess of Württemberg-Neustadt) and Anthony Ulrich, all born from Augustus' second marriage with Dorothea of Anhalt-Zerbst.

Adolf Wilhelm, Duke of Saxe-Eisenach (Weimar, 15 May 1632 – Eisenach, 21 November 1668) was a duke of Saxe-Eisenach.

He was the fourth but second surviving son of Wilhelm, Duke of Saxe-Weimar and Eleonore Dorothea of Anhalt-Dessau.

When Adolf was nineteen years old, he traveled around several countries, in particular France. Subsequently, in 1656 entered the service of King Charles X Gustav of Sweden (who was at that time engaged in the Northern Wars against Poland) as a colonel, where Adolf was characterised by his courage and bravery. However, after a meeting in Funen with an imperial ambassador, Adolf transferred to the Imperial Army with the rank of colonel. In 1661, he traveled again to Sweden, and King Charles Gustav offered him the rank of major general of the infantry with a pay of 2000 talents; Adolf declined.

When his father died (1662) Adolf, with his older brother Johann Ernst, divided the paternal estates. He received Eisenach and its Schloss Wilhelmsburg, with its large garden, where he made his residence. His two younger brothers, Johann Georg and Bernhard, received only incomes from the duchies of their older brothers.

Albert V (24 May 1648 – 6 August 1699) was a duke of Saxe-Coburg.

He was the fifth but second surviving son of Ernst I, Duke of Saxe-Coburg-Altenburg (1601-1675), and Elisabeth Sophie of Saxe-Altenburg (1619-1680). He was born in Gotha. With his brother Bernhard, he attended the University of Tübingen from 1666, and later continued his studies in Geneva. He went on his Grand Tour with his brother Heinrich to Denmark, Sweden and the Netherlands.

When his father died in 1675, Albert became ruler of the duchy of Saxe-Gotha-Altenburg along with all his brothers, and took Saalfeld as his residence. In 1680, after concluding a treaty of partition with his brothers, he received Coburg, to which he moved his residence.

After his death without surviving sons in Coburg, his lands were disputed between his brothers, but Coburg was finally inherited by his youngest surviving brother, John Ernst.
