This stone is in poor condition and the details are not clear, but I believe this to refer to Gabriel Watson's second wife Ann, who was buried 5th 5th August 1780.

The first digit of her age may be a 5 or a 6; if it is read as a '5', this would make her about 16 at the time of the baptism of her first child, and her husband more than twice her age. The top curve of the digit looks more like a '6', which would make her birth year about 1718.
