The Ziadie family is an upper-class family prominent in Jamaica. They are the descendants of half a dozen Maronite Catholic brothers who emigrated from Lebanon.
Lady Colin Campbell, previously Georgia Ziadie, is descended from this family through her father, Michael Ziadie. She says the Ziadies have gone from being "revered to reviled to now treasured as exotic national fruit" and are a wealthy family in Jamaica. The opera director Sir Peter Jonas is her cousin, the son of Hilda May Jonas (née Ziadie), the second of fifteen children of Tewfik Ziadie, Michael Ziadie's brother.
