I have read the biography Fergie her secret life from the author Allan Starkie.In it he mentions that Peggy Caskie was once the girlfriend of John Bryan(Former boyfriend of duchess of York) .Perhaps John Bryan knows where she is.Unfortunatly the author also disclosed that she had a certain illness (which is highly illegal to disclose!)You or Peggy could sue for that.The nature of this kind of illness is very,very confidential.Any illness in fact may not be disclosed whatsoever by anybody at all!!!
