factotum

From that day I became Mr. Moncton's factotum, his confidential clerk, and principal agent.

Such was Mr. Plimmins, Mr. Plaskwith's factotum, foreman in the shop, assistant editor to the Mercury.

Ere long he had been taken into the company as an actor, and was soon spoken of as a ‘Johannes Factotum.’

Peter judged him the factotum of the little household: he knew where the biscuits were kept and the state of the grocer's account.

I hired as errand boy and general factotum to a small grocer down near the market.
