German and Danish: from Middle High German kellaere ‘cellarman, cellar master’ (from Latin cellarius, denoting the keeper of the cella ‘store chamber, pantry’). Hence an occupational name for the overseer of the stores, accounts, or household in general in, for example, a monastery or castle. Kellers were important as trusted stewards in a great household, and in some cases were promoted to ministerial rank. This form of the surname is also established in many other parts of Europe, e.g. in France (Alsace and Lorraine), Russia, Hungary, the Netherlands, Poland, Czechia, and Croatia.
English: occupational name from Middle English keller ‘maker of cauls or kells (women's close-fitting caps or headdresses)’, a derivative of Middle English calle, kelle.
Irish: variant of Kelleher .
