The Museum of the Jewish People: "ZANDMAN. Surnames derive from one of many different origins. Sometimes there may be more than one explanation for the same name. This family name derives from an occupation (also connected with raw material, finished product or implements associated with that trade). The family name Zandman includes the German word Zand, which means "sand", thus was probably attached to a family of constructors or builders. Other related family names are Zhand, Zand, Zamd and Zamed. The name Zandman is common among Jewish families in Ukraine, and also in Oshmyany (Belorussia (today Belarus) and Troki (Lithuania)."
