Many of the small, old cemeteries are now managed by the Jewish Cemetery Association of Massachusetts, JCAM, which has a searchable database. I have learned that you must search multiple variations for a name if you find no matches the first time. Below is what I have found. In this case, the photo means the grave is unmarked. I live about 20 minutes from this cemetery and will be happy to obtain photos for the other two on a warmish day.
