Don,
Your hopes are justified. 99 years ago the Penistone MIs were transcribed and only last year I digitised the transcript for Barnsley Archives & Local Studies. The COTTONs were Gentry, so were able to afford burial in the church itself, and their memorials are in the floor. I will check tomorrow when I attend church, but I suspect that the epitaphs are no longer visible because they are in the north aisle and at one end an office has been walled off and at the other there is now a kitchenette and also toilets. Anyway:
Here lyeth the Body of Susannah COTTON Daughter of Wm and Elinor COTTON of Nether Denby in the Parish of Penyston, who dyed the 22nd and was buried the 25th of October 1677.
Here lyeth the Body of John COTTON Son of William and Elinor COTTON who died the 10th and was buried the 12th of September 1671.
Here lyeth the Body of William COTTON of Nether Denby, Gentleman, who deptd this Life the 13th and was buried the 17th of March Anno 1674. Spe Resurrectionis.
Here was Interred the Body of Anne COTTON, Daughter of Wm and Elinor COTTON of Nether Denby. July 28th 1682.
And also the Body of Mary COTTON, Daughter of the same Wm and Elinor COTTON. December the 25th 1682.
(Nothing for Elinor.)
