Michael Kohn-Zerkowitz likely moved from Prague to Mahr. Weisskirchen, Moravia in the late 1770s. Jewish record books show that he was known both as "Michael Zerkowitz" and as "Michael Kohn", but his name does not appear on Familiant lists. Following the death of his mother in 1809, he and his wife moved to nearby Leipnik, Moravia [now Lipnik nad Becvou, Czech Republic] where his eldest son, Juda Lobl Zerkowitz, had already settled several years before. The Zerkowitz family was considered among the most prominent in Leipnik's Jewish community, and Michael and his wife occupied household #29 in Leipnik's Jewish quarter. Michael Zerkowitz died of inflammation of the lung membranes.

In Hugo Gold's "Jews and Jewish Communites, Past and Present in Moravia" (1929), the following statement is found: "Of the oldest families living in Leipnik for hundreds of years, the family Zerkowitz, No. 29... must be mentioned." For many years, the Zerkowitz plot in Leipnik's Jewish cemetery was marked with a distinguishing arch. Sadly, this no longer exists. In a visit to the cemetery in 2002, descendant Avinoam Zerkowitz found no evidence of any Zerkowitz graves. All had fallen victim to destruction by both the Nazis and then the Fascists behind them.
