Brzósk
Brzósk is a Polish surname. It is likely derived from a topographic name referring to a place overgrown with birch trees (Polish: brzoza meaning birch). It may also have originated as a nickname referring to someone associated with birch trees in some way, either through occupation (e.g., a woodworker specializing in birch) or personal characteristics. Surnames ending in -sk are common in Poland and often denote origin from a specific locality. Thus, an early bearer of the name may have been from a place called Brzózki or a similar variant. The name is relatively common in Poland, with varying frequency across different regions. Further research into genealogical records and Polish onomastics would be required to pinpoint the precise origin and history of a specific Brzósk family line.
