My information and research on the Parkinson Great House has a HUGE gap. I have a friend in Negril who's family supposedly lived in it, ran a spice factory of sorts - unclear so I didn't write about it. Next visit I hope to take her up there (heavily guarded) and get some video of her telling her tale. Meantime...enjoy!
