DENNISON Family History

This English and sometimes Scottish surname is of Ancient Greek origins. It derives from the medieval given name Dennis, itself coming from the Greek Dionysios meaning "the divine one of Nysa". Better known as Bacchus, this god was protector of the vine. Nysa was a mountain in the modern Afghanistan where celebrations were held in the god's honour by the Greek army. The name was recorded as Dionisius in documents relating to the Danelaw, circa 1100, and Denis de Sixlea appears in the 1176 "Pipe Rolls" of Lincolnshire.
