Harnoncourt-Unverzagt is the name of an old Austrian noble family, which came to Austria from the Duchy of Lorraine, but originated from Luxembourg.

History

Counts d'Harnoncourt intermarried with Unverzagt family in the 18th century when Joseph Ludwig Matthias de la Fontaine, Count of Harnoncourt (1736–1816) married Countess Maria Leopoldine Unverzagt (1754–1835), who was the last of her line. Their son Count Herbert Ludwig de la Fontaigne, Count of Harnoncourt (1789–1846), took over her coat of arms in 1839 and called himself Graf von Harnoncourt-Unverzagt. All members of the family have descended from him and his wife, Countess Sophie von Haugwitz (1798–1859).
