My father-in-law came from Kastellorizo to Sydney when he was about 16 [1929?] with his family. He had 9 brothers [one of which was called Peter] and 1 sister. He spelt his surname Nitties. Some of the family moved to Melbourne. If this looks like being of some help please don't hesitate to contact me. His father was Demetrius Nitties & his mother Kyraiki Lazos.
