Majordomo

Typically, this is the highest (major) person of a household (domūs or domicile) staff, a head servant who acts on behalf of the owner of a large or significant residence.

[1] Historically, many institutions and governments – monasteries, cathedrals, and cities – as well as noble and royal houses, also had the post of majordomo, who usually was in charge of finances.

Additionally, the Hispanos of New Mexico use the related term mayordomo to refer to the manager of an acequia system for a town or valley.

The origin is from maior domūs (Latin for 'principal of the house'), and it was borrowed into English from Spanish mayordomo or Old Italian maiordomo.

In the original run of the nighttime drama Dynasty, the majordomo of the Carrington residence is Joseph Anders, played by Lee Bergere during seasons 1–3.
