I note Edmund Bartlett had a daughter Polly Pierce Bartlett in Amesbury born sometime around then or maybe a few years later.
I would bet that Bayley Clough got his first name from a close ancestor.
John Bayley married Eleanor Emery, daughter of John Emery of Newbury.The emerys and Bartletts intermarried a number of times.
The name Bayley Clough rings a bell.I recently went through graves stone photo of Walnut Hill Cem in West Newbury which many of my Bartlett ancestors are buried. I don't know if that's why Bayley Clough sticks in my mind or if it was somethingelse.
Unfortunately, there is no transcription so one much try to read the stones.
