Marquess of Heusden (Dutch: Markies van Heusden) is a high-ranking Dutch title of nobility retained by the Earl of Clancarty.[1]
The 2nd Earl of Clancarty, an Anglo-Irish peer, was credited with resolving various border disputes in the Netherlands, Germany and Italy at the Congress of Vienna (1814 – 1815) and in his role as Ambassador to the Netherlands. For his service as ambassador to The Hague, he was raised into the Dutch nobility with the creation of the hereditary title Markies van Heusden (Marquess of Heusden) by King Willem I of the Netherlands (royal decree 8 July 1815 no. 14).
