Crown Prince Friedrich Ludwig Wikipedia
He was the only son of Duke Eberhard Ludwig and Johanna Elizabeth, daughter of Margrave Frederick VII of Baden-Durlach.
Friedrich Ludwig, however, died before his father, who survived him until 1733. With his death, without male heirs, the main line of Wurttemberg became extinct and the duchy passed to a collateral line of Wurttemberg-Winnental.
On December 8, 1716, Frederick Louis, married Henrietta Maria, daughter of Margrave Philip William of Brandenburg-Schwedt, with whom he had children:
1. Eberhard Friedrich (1718–1719)
2. Louisa Friederike (3 February 1722 – 2 August 1791), who married Duke Friedrich II of Mecklenburg-Schwerin
