I am trying to find out the origin of the name Hadzidakis. My grandfather was a Greek ousted from Asia Minor in 1912. I understand the prefix Hadzi was added to the given name of someone who visited the Holy Land. However, I can't find an ancestor with the name Dakis. Could Dakis be a nickname for Antonios or Demos? Has anybody ever heard of the Greek name of Dakis? Did everybody in the family give up their family name and then go by this new name? Thank you.
