The name is derived from the Polish place name (settlement name) Kuchary with the suffix -ski and refers to a place of residence, origin or estate. It may also be derived from the common noun kucharz meaning ‘cook’ and refer to an occupation. Alternatively, it may also be derived from the Polish personal name Kucharz with the suffix -ski, imitating the structure of surnames derived from place names with the same suffix, and refer to the connection with the father or another ancestor by that name.
