Marriage and issue

In 1751 he married, morganatically, Maria Johanna Camasse (1734–1807, created Countess Forbach in 1757). They had six children, who were unable to succeed to their father's Duchy due to the morganatic nature of their parents' marriage at first, but in 1792 were allowed to carry the name Freiherr von Zweibrücken:

Christian, Count of Forbach, Marquis of Deux-Ponts (1752–1817), Royal Bavarian General der Infanterie

Karl Ludwig, Baron of Zweybrücken (1759–63)

Elisabeth Auguste Friederike von Zweibrücken (1766–1836)
