Thanks for posting the photo. In Latin denuntiationes (plural) has this range of meanings:
announcement/notification/indication; warning/threat; denunciation/allegation;
declaration (war); injunction; admonition; summons, formal legal notice;
If we consider the meaning to be announcements or notices, minus the pejorative sense prevalent in the English definition, then an entry of Three seems likely to refer to banns (as heywood has suggested).
However I'm only speculating. You need an answer from someone with expertise in these records.
