Eugen Erwein von Schönborn-Heusenstamm

Upon his birth, he became reigning Count of the County of Schönborn-Heusenstamm, a German statelet formed in 1717 as a partition of Schönborn (in the south of modern Hesse, Germany). The County included Heusenstamm Castle [de; fr] which had been built in 1661 by his grandfather, Baron Philipp Erwein von Schönborn.^[8] He expanded the family's significant holdings considerably. He inherited the Weyerburg estate and the Mautern an der Donau estate from his uncle. In 1766, he also bought the Rossatz estate, not far from Mautern. He bought Hessenstein Castle and the large Hungarian estate of Munkács from his uncle, Rudolf Franz. In Munkács, the Count built a hosiery factory and a sizable stud farm. In 1782, he built a bridge over the Latorica river.^[9]

After receiving his education, he became an Imperial Privy Councillor and Chamberlain and Supreme Hereditary Cupbearer of Austria. In 1790, he received the Order of the Golden Fleece.^[9]

In 1751, the Count married Princess Elisabeth Josepha zu Salm-Salm (1729–1775), a daughter of Prince Nikolaus Leopold zu Salm-Salm.^[10] The couple had five daughters and two sons, including:^[9]

• Marie Christine von Schönborn (1754–1797), who married Count Franz Stephan von Silva-Tarouca.^[11]
• Amalie Ludovica von Schönborn (1756–1802), who became a canoness in Mons.^[12]
• Maria Theresia von Schönborn (1758–1838), who married Count Johann Rudolf Czernin von und zu Chudenitz.^[13]
• Elisabeth Franziska von Schönborn (b. 1759), who became a canoness in Thorn.^[12]
• Maria Franziska von Schönborn (1763–1825), who married Franz Joseph von Sternberg-Manderscheid in 1787.^[14]
• Wilhelm Eugen von Schönborn (1765–1770), who died young.^[12]
• Marquard Wilhelm von Schönborn (1766–1769), who died young.^[12]

After the death of his first wife, he married Princess Marie Theresia of Colloredo (b. 1744) in 1776. The marriage remained childless.^[9]

Schönborn died on 25 July 1801 in Vienna. Since both of his sons died as children and his daughters could not inherit, the estates fell to the older, or Franconian line, whose founder was Count Rudolph Franz Erwein.^[9]
