Doubleday Family History

English (Nottinghamshire Lincolnshire and Norfolk): either a nickname or an occupational name from the Middle English adjective double ‘pair of similar things’ or the noun ‘twin’ + daie ‘dairyman dairywoman’. The sense is uncertain perhaps ‘one of a pair of dairymen or women’ or ‘one who doubles up as a dairyman or dairywoman’ or even one of a pair of twins who were dairy workers though this is less likely since the surname seems to have arisen independently in several counties.
