The Wrong Jakub: NOT the son of Kašpar Lieberzeit
The book "Stochov rodiště sv. Václava" ("Stochov birthplace of St. Wenceslas") provides details for every residence in the village of  Čelechovice (northwest of Prague, near Mšecké Žehrovice). Blanka Lednická has transcribed these entries on a web page at  https://www.celechovice.eu/o-celechovicich/blanka-lednicka-kniha-stochov-rodiste-sv-vaclava/
The water mill was #36 in the village, after numbering had been established. The text for the Mill at #36 states:
"Po odchodu Eliáše Grünera se stal panským mlynářem na čelechovickém mlýně Jakub, syn hřešického mlynáře Kašpara Lieberzeita."
"After the departure of Eliáš Grüner, Jakub, the son of the Hřešice miller Kašpar Lieberzeit, became the master miller at the Čelechovice mill."
(Note that the inclusion of the letter "r" in the surname is a later addition. The "r" was not used by those recording the family of Kašpar Liebezeit in the Seigniorial Registers until 1730. And even after that, the inclusion of the "r" was not consistent and was not used at all in the Hřešice registers of the 1760s to 1780s.)
No date of departure is given for Eliáš Grüner, but the same entry says that he bought the mill at Kalivody (which had been the Liebezeit family mill at one time, although the text does not mention that) where he had already by 1722 been the miller for some time. So, the departure of Eliáš Grüner from Čelechovice was some time before 1722.
The problem with this timeline is that Jakub, the son of the Hřešice miller Kašpar Liebezeit was born 2 Aug 1712 (Mšec 02/28 at https://ebadatelna.soapraha.cz/d/8934/28). So, this Jakub was only 10 years old when Eliáš Grüner bought the Kalivody mill.
Furthermore, Kašpar Liebezeit's son Jakub remained in his childhood home at Hřešice through the 1745 Seigniorial Register when he was age 31 1/4. So, he had not moved to the Čelechovice mill, which had been without Eliáš Grüner for more than 20 years by then. So, clearly the Jakub Liebezeit who by 1722 became the master miller at the Čelechovice mill was NOT the 1712 Jakub who was the son of the Hřešice miller Kašpar Lieberzeit.
The book possibly contains further confusion of two different men named Jakub Libezeit with the next sentences:
"Roku 1750 koupil dům v Novém Strašecí. Po Jakubově smrti koupila mlýn roku 1759 vdova Anna od knížete Schwarzenberka. Anna Lieberzeitová se znovu provdala za Václava Volfa z Hřešic, se kterýhm pak na mlýně hospodařila celých třicet let. Roku 1789 zdědil mlýn syn Jakuba Lieberzeita Antonín, který se oženil s Marií Annou, dcerou Václava Vítocha, mlynáře kačického. Po Antonínovi patřil mlýn jeho synovi Antonínovi (od roku 1826). Ve 40. letech 19. století Antonín o mlýn přišel, ale roku 1846 mu ho vrchnost musela vrátit. Roku 1871 koupil zadlužený mlýn od Emanuela Lieberzeita Antonín Dvořák."
"In 1750 he bought a house in Nové Strašecí. After Jakub's death, his widow Anna bought the mill from Prince Schwarzenberg in 1759. Anna Lieberzeit remarried to Václav Volf of Hřešice, with whom she managed the mill for thirty years. In 1789 the mill was inherited by Jakub Lieberzeit's son Antonín, who married Marie Anna, daughter of Václav Vítoch, miller in Kačice. After Antonín, the mill belonged to his son Antonín (since 1826). In the 1840s, Antonín lost the mill, but in 1846 the authorities had to return it to him. In 1871, Antonín Dvořák bought the debt-ridden mill from Emanuel Lieberzeit."
The Jakub who bought the house in 1750 could well have been the son of Kašpar Liebezeit, but even if he was he clearly was NOT the master miller at the Čelechovice mill before reaching the age of 10 and while still being shown in his father's home at Hřešice as late as 1745. So, in addition to the question of who was the miller at he Čelechovice mill in 1722, we also have the question of which Jakub Liebezeit married Anna and bought a house in Nové Strašecí in 1750?
So, who was the miller at the Čelechovice mill in 1722 after the departure of Eliáš Grüner as the miller?
