How Greek names are chosen
Greek naming is close to an algorithm, which is why the same names recur down a family for centuries: the eldest son takes his paternal grandfather's name and the eldest daughter her paternal grandmother's, with later children drawing on the mother's side. The name is usually settled within the first week or ten days, the christening following at around forty days, and by custom the godfather has the final word. Because so many names are saints' names, most Greeks keep a name day — the saint's feast — as well as a birthday, and it is often the more sociable of the two. Regional patron saints show up plainly in the distribution: Spyridon clusters on Corfu, Gerasimos on Kefalonia, Dionysios on Zakynthos.
