DOBELL
As described in historical dictionaries
Patronymica Britannica (1860)
DOBELL. Perhaps originally from the Roman personal name, Dolabella. The French have always been fond of adopting classical names, and this occurs as a surname in Normandy in the twelfth and thirteenth centuries in the form of Dolbell. In 1296, however, it is found in Sussex as De Dobel, implying a local origin, and in the sixteenth century the family ranked with the gentry of that county, bearing the canting arms of a Doe between three Bells.
