Crown Jeweller
Queen Victoria created the official position of Crown Jeweller in 1843, although before that there were various freelance jewelers she and other monarchs utilized. The Crown Jeweller cleans up and fixes any of the crown jewels that might be in rough shape.
Master of the Horse
A largely ceremonial position nowadays, this role consisted of taking care of all aspects of the stables and coach houses, along with his underlings who helped with such things. At one point this position also took care of all of the hounds and other animals in the house, but the position was split around the late 1800s.
