What does Georgios mean?
Greek form of George, from 'georgos' ('farmer, husbandman'), itself from 'ge' ('earth') and 'ergon' ('work'). Borne by Saint George.
What does Ladon mean?
Greek Ladon, the serpent-dragon coiled around the tree of the golden apples of the Hesperides. Flag: a mythological dragon's NAME, not a literal 'dragon' word; its etymology is uncertain (one guess links it to a root 'to flow strongly', and Ladon is also the name of a river-god), so it is included as the name of a dragon.
