Surname or Lastname
English (chiefly Kent and Sussex)
English (chiefly Kent and Sussex) : occupational name for a designer or engineer, from a Middle English reduced form of Old French engineor ‘contriver’ (a derivative of engaigne ‘cunning’, ‘ingenuity’, ‘stratagem’, ‘device’). Engineers in the Middle Ages were primarily designers and builders of military machines, although in peacetime they might turn their hands to architecture and other more pacific functions.German : from the Latin personal name Januarius (see January 1). Jänner is a South German word for ‘January’, and so it is possible that this is one of the surnames acquired from words denoting months of the year, for example by converts who had been baptized in that month, people who were born or baptized in that month, or people whose taxes were due in January.

Compare German Bruehl.German : from Middle Low German brill ‘eyeglasses’, hence a metonymic occupational name for a maker of spectacles or perhaps a nickname for someone who wore them.Jewish (Ashkenazic) : acronymic surname from Hebrew ben rabi ‘son of …’ and the first letter of each part of a Yiddish double male personal name, most likely Yude (Juda) Leyb. Many Ashkenazic family names beginning with Br- and Bar- are probably of acronymic origin, but without detailed evidence from family histories it is impossible to specify the personal name from which each is derived.
