The Klinštejn family became involved in the dispute between the Bohemian king John of Bohemia and the Czech nobility after the imprisonment of the nobleman Henry of Lipá in 1315.

[2] Smil, called Světlický, left behind three descendants: a daughter, Scholastika, a nun in the Doksany monastery, an older son, Častolov, and a younger, Jindřich, who held the office of royal burgrave in Budyšín in 1232–1237.

[3] In 1291, Záviš was referred to as the burgrave of Houska, and at that time he renounced his paternal rights over the villages of the Doksan Monastery - the records include Horní and Dolní Police, Stoupná, Bělá and Grundis.

At the beginning of the 14th century, Záviš or his descendants held Žandov, Skalice, Horní and Dolní Libchav, Častolovice in their possession outside of Klinštejna, Radeč and maybe others.

[7] On 23 May 1362, Bohuněk, the knight from Klinštejn (Bohunko, Ritter von Klingstein) appointed Mikuláš (Nikolaus), who had previously worked in Zwickau, as parish priest in Skalice (Langenau).

[7] Soon after Bohuňek's death on 2 December 1363, Záviš from Klinštejn (Zawistonis de Clynngenstein, also Sawisto) and his brothers installed priest Jakub (Jakob) in Horní Libchavy for the deceased pastor Jan (Johann).

[7] Two years later (31 May 1372), the brothers from Klinštejn introduced Hynek, Jindřich (Heinrich), Bušek, Zdeněk, Henzlín, Frydman (Fridmann) and Půta from Žandov (for the orphans of their brother Závis from Klinštejn) to the Church of St. James the Great in Horní Libchava for the deceased priest Jan (Johann), son of Herbard from Lípa.

In the records of that time, the family was also listed as Míčan of Klinštejn and Roztoky (German: Mičan von Klinstein und Rostok, Czech: Míčanové z Klinštejna a z Roztok).
