Eberhard Ludwig of Württemberg was the first Duke who lived openly with a mistress,
Wilhelmine von Grävenitz (1686–1744). His
morganatic marriage to her 1707 was considered a scandal. On the application of Johanna Elisabeth to
Holy Roman Emperor Charles VI, the bigamous marriage had to be dissolved and Grävenitz was sent into exile in Switzerland. Her spouse returned in 1710 when Wilhelmine of Grävenitz, through a sham marriage to Hofmeister Count von Würben, was able to return to Württemberg as well. They lived largely in Ludwigsburg. In 1718, the residence was also officially moved to Ludwigsburg. Johanna Elisabeth, meanwhile, continued to live in the Old Palace in Stuttgart. She refused, however, to file for divorce, and the marriage was not dissolved. The early death of Prince Friedrich Ludwig in 1731 threatened to move Württemberg to a Catholic secondary line. Because of this danger, Duke Eberhard Ludwig broke his connection to Wilhelmine of Grävenitz and hoped to conceive an heir from his legitimate and long-ignored wife, Johanna Elisabeth. The advanced age of the couple and the imminent death of the Duke on 31 October 1733, however, thwarted these efforts. Johanna Elizabeth survived her husband by more than twenty years. She lived as a widow at Kirchheim Castle, and died in Schloss Stetten, Stetten in the Rems Valley. She was buried in the Ludwigsburg Castle Church. == Children ==
