Manndorff zu Pfannhofen und Wissenau
von und zu Manndorff zu Pfannhofen und Wissenau are an Austrian nobility family, more specifically the Uradel (old nobility). They are among the oldest Carinthian noble families still in existence today. Origin. Besides the Metnitz family, the Manndorffs are the oldest non-extinct family belonging to Carinthian nobility. The spelling of the name changed between Manndorff, Manndorf, Mandorf, Mondorf, Monsdorf, Mansdorf, and Manstorff. The first bearer of the name, Harte Manus miles de Mondorf, appears mentioned in February 1214 before Acre in the Kingdom of Jerusalem as a witness to a deed of gift from  the Wicard of Karlsperg, who transferred one of his Carinthian estates to the St. Johannis hospital in Jerusalem. Besides this Manndorff other members of long-established Carinthian nobility, namely Silberberg, Gurniz and Perneck—who were on a pilgrimage in the Holy land with the Wicard of Karlsperg--, were also witnesses to the deed. The exact origin of this first Manndorff and his ancestors remains unclear. In a legend—written down in the castle of Manndorf in the year of 1688 by Freiherr Georg Siegmund, Baron von und zu Manndorff—titled "Manndorferischem Stamen Paumb" (loosely translated from German "Family Tree of  the Manndorff's"), the Duke of Württemberg in 1118 acquainted a big and wild man, who the Prince married to a tall woman. After they had many children, most of them male, the Prince gave them all a village and called them Manndorff. Thereafter the Prince of Württemberg had a war for which he called onto many Manndorff's, who measured well and honorable in battle. The Prince then upraised the Manndorffs to nobility, and in the shield (referring to the coat of arms), gave them a naked, wild brave man including 3 spears. There is no historical evidence for  this story. Many more Manndorffs are documented in Carinthia in the 13th and the 14th century and the family is documented in the official Carinthian nobility register of the years 1446. Hans von und zu Manndorf, Lord on Manndorf, Gurnitz, Waldenstein, Wiesenau, and Flaschberg, Imperial General Collector in Carinthia, was recorded on January 3, 1625 in the country council of Carniola. The Manndorffs received the status of "Reichs- und erbländisch-österreichische Freiherrenstand" (Free lords of the realm and inherited Austrian lands) from Emperor Ferdinand III. in Ebersdorf on September 15, 1644 through "Herr auf Pfannhoffen und Wißenau" and the merging  of the coat of arms of with the now extinct Haßlinger zu Pfannhofen und Seepüh and the now also extinct von Pibriach zum Biberstein. Possessions. Over the centuries the Manndorffs acquired the following dominions, estates, and castles in Carinthia. More family possessions existed in eastern Tyrol, Carniola (modern Slovenia) and Hungary. Hans Manndorff founded the monastery Maria Luggau in 1520 in the valley of Lesachtal. Around the year 1500 he remodeled the estate Edling at Kotschach in the upper Gail Valley in Carinthia to a castle which he called "Manndorf". Castle Manndorf is considered to be one of the first  castles in Carinthia People. Many other Manndorffs became deputies to the Carinthian state parliament. The coat of arms of the family Manndorff is represented five times in the hall of coat of arms inside the "Landhaus" (palace of the estates) of Klagenfurt. Through the marriage of Anton Konrad (1797–1866) with Anna Maria Countess of Esterházy-Galantha a Transylvania -based Hungarian line of the family Manndorff was created, which became extinct with the death of Anton (1922–1978). Through marriage of Dr. Maximilian Manndorff with Albertine von Mannlicher (1893–1957), all surviving bearers of the name Manndorff are also descendants of the inventor  and arms designer Ferdinand, Knight of Mannlicher.
