The Orlando (Fla.) Sentinel said town employees sent the film star couple a message of condolence following 16-year-old Jett's death of a seizure in the Bahamas.
Travolta and his wife, who own a home in Ocala, had previously been supportive of Lady Lake, donating $15,000 to tornado victims in 2007 and helping to raise another $15,000.
The Sentinel said the Travolta family sent a letter thanking the town for its "thoughts and prayers," which they said comforted them during their ordeal.
"This is a time that we've needed our friends and family more than ever and this is a time that you were there and thinking of us," said a note signed by John, Kelly and Ella Travolta. "We deeply appreciate it, but mostly for our sweet Jetty boy."
