Roker Family History

German (also Röker): of uncertain origin. In the north, it may be from a short form of a Germanic personal name from hrok ‘rook’, or alternatively from an agent derivative of Middle Low German rok ‘smoke’ and hence an occupational name for someone who smoked fish or meat or for a blacksmith or charcoal burner. In the east it could be an occupational name for a beekeeper, from Slavic roj ‘swarm of bees’.
