If you have ancestors who might be buried in Rhode Island, check out the Rhode Island Cemeteries Database. It is a massive data transcription project that began in 1990. Find your Rhode Island ancestors at: http://ricemeteries.tripod.com/index.html
You can also find it here (not sure if there is any difference):
