Friedrich Karl, born in Mheer (Province of Limburg) on 06. August 1787 to Edmond and Alexandrine, née Countess von Merveldt, on 14 May 1816 weds the nearly 13 year younger Countess Luise Wolff-Metternich zur Gracht in the Münster Cathedral.
Four years after Luise’s death on 27 August 1837 in Cologne, he marries the widow, Baroness Sophie von Fürstenberg (*18 July 1790) in Füchten on 24 April 1841. She had previously been married for nearly 18 years to Joseph von Mollin, who died in 1837.
No significant construction measures fell into Friedrich Karl’s time, as his parents and grandparents had already substantially modified the main house and associated buildings.
He probably also lacked the necessary financial means, as it was up to him, to reverse – as far as possible – the defacto splitting (effected under French inheritance law), which resulted in the weakening of the estate. He succeeded in purchasing back substantial parts of the inheritances which had fallen to his sisters, or to have them given back to him.
On the other hand, independent family branches developed from his brothers’ inheritances, inter alia Phillipe (Mheer, Province of Limburg), which still exist – in part – today.
