András Temérdek (Kisjeszen branch)|
Mágya (Nagyjeszen branch)
The first known ancestor of the Kisjeszen (Minor Jeszen) branch was the castle warrior András Temérdek who received lands in Túróc (Slovak: Turiec) county from king Béla IV of Hungary in 1255. The family introduced their new surname after the name of a village "Jeszen". In the 14th century the family used the "Kisjeszeni" name form and the Slavic variant of their name "Jeszenszky" came into use only from the 15th century. While the word jesen means "autumn" in several Slavic languages, the Slovak name of the village, Jaseno, actually derives from the word jaseň, "ash tree".
The first known member of the Nagyjeszen (Major Jeszen) branch was called Mágya. In 1278 Mágya received his noble title, because of his valor in the Battle on the Marchfeld.
Famous members of the families
Ladislaus Jesenský died in 1526 during the catastrophic Battle of Mohács. Subsequently, all Jesenský property was confiscated by the advancing Ottomans, so brothers Melchior, Lorenz and Balthasar Jesenský moved to Silesia (then part of the Crown of Bohemia) and lived in Wrocław and Świdnica from 1541 onward. Balthasar's son was Ján Jesenský, known as Jan Jesenius, famous scientist and politician who lived and died in Prague, Bohemia.
