Yeoman

Sponsorship the way you would do it
"Yeoman" is an antiquated term for farmers, tradesmen and other members of the early English middle class. The term suggests someone upright, sturdy, honest and trustworthy.

Yeoman is also a naval occupation, roughly equivalent to a secretary.

Compare Yeomen of the Guard.

A Gilbert and Sullivan operetta was entitled Yeomen of the Guard.

In the British Army during World War 1, the Territorial cavalry regiments were designated Yeomanry (for example, 'The 1/1st Warwickshire Yeomanry Regiment') though as the war progressed many regiments fought as dismounted infantry.
