Hmmm, I've found it in the banns, but unlike the other entries, no date is written in to show that they actually married:
https://familysearch.org/pal:/MM9.3....57302,30476401
Banns of Marriage between Robert Fox Batchelor and Mary Hooks Spinster both of this Parish ...14th Oct 1764, 21st Oct 1764, 28th Oct 1764.
I guess it is a different couple, then.
