Good Kleinsiersdorf

The estate Kleinsiersdorf is a manor located northwest of Würm, Geilenkirchen. It lies by the Wurm, is surrounded by moats, and is connected to the village via the path Zum Wassergut. The estate is listed as a historical monument.
In 1397, the estate Klein-Siersdorf came to Hermann von Randerath and his wife Margaretha von Wachtendonk, which had belonged to Sander von Siersdorf in 1352. Subsequently, the namesake son Hermann von Randerath and his wife Lisa von Oetgenbach, and then their son Heinrich von Randerath and his wife Barbara von der Hoyve owned the estate Klein-Siersdorf. Around the middle of the 16th century, the descendants of Sophia von Randerath, who was married to Johann von Hochsteden, inherited Klein-Siersdorf after Sophia's brother Heinrich von Randerath at Klein-Siersdorf and his wife Barbara von der Hoyve passed away without leaving legitimate heirs. The von Hochsteden family still owned it in 1588. In 1599, Klein-Siersdorf came to the Wolff von Randerath through the purchase of the estate by Goddaert Wolff von Randerath. After this, the estate first went to his son-in-law Thomas Borken and in the early 17th century to his son-in-law Wilhelm von Fürth, known as Brewer. The outer courtyard still dates from the 16th century, while the manor house was rebuilt in the 18th century. Around the 1860s, Theodor Freiherr von Fürth sold Klein-Siersdorf to the merchant Asser, who subdivided it, from whom the Counts of Mirbach-Harff acquired the remaining estate. In 1904, Count Wilhelm von Mirbach-Harff is mentioned as the owner.
