I'm researching in Aguadilla and found 2 indices: marriages and deaths at the LDS site: familysearch.org; Caribbean, Central and South America; Puerto Rico; Roman Catholic Church Records. You have to browse through the pages and there's no guarantee that they still have the records. I'm contacting them to find out what's available. The indices are in date, then alpha order. At least, you can get within a 5-year span, or so.
