In mid-18th century Russia a house serf was usually addressed by a diminutive-derogatory form of his/her first name, eg: Van'ka instead of Ivan, Mashka instead of Maria, etc. When a master wished to show special respect to distinguished or talented servants, he might address them by their full first names: Ivan, Maria, etc. Another form of respectful address of elderly and distinguished servants was by their patronymics, eg Petrovich, Egorovna etc. Addressing servants by family names was very unusual at that time.
