The genus appears for the first time in 1236 as a branch of the stango appearing in Pomerania . It was initially called "Maul", then after the homonymous estate near Rhaden Legendorf or Logendorf (Mgkowo in Polish), which is why it was also called Mgkowski and Legendorf-Mgkowski. Paul von Legendorf , Bishop of Warmia, is said to come from this time . In the 15th or 16th century the family was enfeoffed with the Steinort wilderness. Later the name changed to Lehendorf and then to Lehndorff. The family was elevated to the rank of imperial count in 1687 .
The first Lehndorff gentlemen on Steinort included a governor from Preussisch Eylau and an governor from Oletzko . The oak avenues in Steinorter Park, which are now almost 400 years old, are said to go back to Meinhard von Lehndorff (1590–1639), Lieutenant Colonel and District Administrator von Rastenburg , and the builder of the Baroque palace , Eleonore von Dönhoff . An oak tree should have been planted every time a child was born in the family.
