The family can be traced back to at least the early 15th century, when a Jindřich Mičan von Klinstein was active in northern Bohemia.
[1][2] In the records of the 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).
In 1569, Friedrich bought the rest of the estate's granary from the brothers Jan and Zdislav Abdon Kolowrat-Bezdružický.
Friederich also sold parts of Čelechovic estate to Georg Borzita von Martinitz in 1578.
After Albrecht's death it passed to the latter's wife, Magdalena Mičan (née von Hodkowa).
