Ondrusek

Ondrusek is a surname of Czech or Slovak origin. It is a patronymic surname, meaning it is derived from a given name. It is believed to be derived from a diminutive form of the given name Andrew (Ondrej in Czech and Slovak). Therefore, Ondrusek essentially means "son of little Andrew" or "descendant of Andrew."

The surname Ondrusek is found primarily in the Czech Republic and Slovakia, with smaller populations also in other countries due to emigration. Records of individuals with the name can be found in historical documents such as census records, parish registers, and immigration lists.

Variations of the name may include Ondrus, Ondracek, and Ondra. Similar patronymic surnames from the same root exist in other Slavic languages.

The surname is not associated with a specific profession, region, or noble lineage, but rather represents a common family name within the Czech and Slovak population. Genealogical research is necessary to trace the specific origins and history of any particular Ondrusek family.
