Life
Catherine was raised at Dillenburg. In 1560, she married Günther XLI, Count of Schwarzburg-Arnstadt and she moved with her husband to Arnstadt. The marriage was childless, but she reportedly had a good relationship with her husband. They were also on good terms with her brother William. In 1574, they traveled to Breda to mediate between him and the Habsburg monarchy, Habsburg government. This attempt was not successful. Catherine and her husband lived with William in Antwerp, where she continued to live after Günther died. She was present in Delft when her brother was assassinated by Balthasar Gérard. She then took Countess Catharina Belgica of Nassau, Catharina Belgica, a daughter of William and Charlotte of Bourbon, with her to Arnstadt. In 1593, she tried to settle a dispute between Maria of Nassau (1539–1599), Maria of Nassau and Maurice, Prince of Orange over the legacy of their father William. She was not successful, but did succeed in mediating between Louise de Coligny and John VI, Count of Nassau-Dillenburg, who had disagreed over the future marriages of William's six daughters by Charlotte of Bourbon. As a widow, Catherine collected books and gave to charity. She died in Arnstadt in 1624.References
