Have you tried a search for those names through the "search" link just above and to the right of your message? This will bring up a list of links to any messages that may have been posted regarding them already. I just tried one but with no success. Perhaps later someone will make a posting either on this thread or elsewhere.
Meanwhile, you might also want to visit http://www.compusmart.ab.ca/minikitty/missing.html
which contains a list of missing and found people (which I also searched) thanks to "Kathy in Canada" who is working triple-time to keep it up to date. I hope you find the information you are seeking and soon!
Some other sites you may want to see are the thread "CLICK HERE TO DONATE TO THE SAN PEDRO & CAYE CAULKER TOWN COUNCIL RELIEF FUND " at http://ambergriscaye.com/message/Forum2/HTML/001695.html
"Have you or your friends been to Belize?" at http://ambergriscaye.com/message/Forum2/HTML/001846.html
"Belize Emergency Net" at http://www.belizeemergency.net/
"Hurricane Keith Relief" at http://www.ambergriscaye.com/towncouncil/keith.html
