where is yvette?

Iam trying to find Yvette unfortunatly Idon't have a surname (I can't remember it ) we were friends about 18 years ago when we met in Greece where we both worked for a woman with twin girls Yvette lived in in a town called Kiffisia but i stayed with a relative At the time she had a boyfriend called Dion who was home in SA doing service with the police there . she said that her father either sold or made christmas decorations in ( i think johannesburg) I know it's a long shot but I would love to hear from her and catch up on old times
