Frederick Charles, Count of Erbach-Limpurg (21 May 1680 – 20 February 1731), was a German prince member of the House of Erbach and ruler (through marriage) over the Lordship of Limpurg-Michelbach and (through inheritance) over Erbach, Freienstein, Wildenstein, Michelstadt and Breuberg.
Born in Erbach, he was the fourteenth child and sixth (but third surviving) son of George Louis I, Count of Erbach-Erbach and his wife Countess Amalia Katharina of Waldeck-Eisenberg, a daughter of Philipp Dietrich, Count of Waldeck-Eisenberg.
After the death of his father in 1693, Frederick Charles and his surviving older brothers inherited all the Erbach-Erbach domains; however, as the last surviving son of sixteen children, he was still a minor and the government of the lands and legal guardianship were held by the oldest brother Philipp Louis, who managed to rule alone even after his brothers attained majority.
On 18 May 1711 Frederick Charles married Sophie Eleonore (10 June 1695 – 28 January 1738), youngest daughter of Vollrath, Schenk of Limpurg-Speckfeld in Obersontheim.
[citation needed] They had four children: As Sophie Eleonore was one of the five surviving daughters and co-heiresses of Vollrath of Limpurg,[1] when her father, died in 1713 Frederick Charles received the Lordship of Michelbach as part of the inheritance, and the rights to assume the arms and titles of Limpurg (mitregierender Count of Limpurg-Obersontheim).
