I will be in Negril the end of August. Though I am staying on the cliffs, I plan on a day on the beach to search for some old friends. If I can find the woman you are looking to contact I will pass on the information.
FYI you mention sending things to them periodically. If that were me I would do some research on the postal system there, it is nothing like here. They do not have address delivery. There are not post offices as we are used to. Things mailed there have a way of never making it. IF received I believe there could be a problem with customs, the receiver may be required to pay on the item/ items whether it be new or used. Anything coming onto the island permanently is subject to fees/duty
