At the beginning of the 16th century, the von Lehndorff family, who were resident in the Königsberg area, were enfeoffed with a large piece of land called the "Steinort Wilderness". Many neighboring places were part of it. The place with the associated estate is also the ancestral home of the von Lehndorff family. Ahasuerus, born in 1637, was his successor at Steinort. His third wife Eleonore had the manor built. His son Ernst Ahasuerus took over the successor. From 1758 his son Ernst Ahasverus Heinrich (* 1727) continued the line. His son Carl Ludwig was born in 1770 and then took over Steinort. He had five children. The eldest son Carl Meinhard took over Steinort in 1854. Carl Meinhard married his cousin Anna, née Countess Hahn-Basedow, who after his death in 1883 took over the management of the property until her son Carl Meinhard came of age. This Carl Meinhard ("Caroll") remained unmarried. Since he was childless, the property passed to the Preyl line of his uncle Heinrich in 1936 (after his death). The younger, Manfred, inherited from his two sons (the older, Heinrich, had died in the First World War). Manfred renounced and handed it over to his son Heinrich Graf von Lehndorff, who was executed for his involvement in the assassination attempt on Hitler in 1944. Since Heinrich's brother Ahasuerus had died in the war, Count Hans von Lehndorff (cousin von Heinrich) could have continued the line. Source: Wikipedia
