Family name origins & meanings

  • Spanish : from the personal name Diego, which is of uncertain derivation. It was early taken to be a reduced form ofSantiago, and is commonly taken by English speakers as being a form of James, but this is no more than folk etymology. It is found in the Middle Ages in the Latin forms Didacus andDidagus, which Meyer-Lübke derived from Greekdidakhē ‘doctrine’, ‘teaching’, but in view of the fact that it is unknown outside the Iberian Peninsula it may possibly have a pre-Roman origin.
