Hi Rob
I followed Crystal's example and wrote the marriage entries down word for word.
This means I looked at John Turner's marriage to Ann again and here's the full entry (I should have done this the first time!!)
St Marys & St Chad's, Brewood,
John Turner of the parish of Stoke in the County of Stafford, Potter and Ann Emery of this parish, spinster were married in this church by License with the consent of her father this fifteenth day of October one thousand seven hundred and fifty nine by me Richard Fenton Vicar. This marriage was solemnized between us John Turner and Ann Emery. In the presence of Richard (can't read surname) and Sam: Emery. They all signed.
Here's Samuel and Sarah's marriage.
St Marys, Stafford
Samuel Emery of the parish of Brewood, and Sarah Turner of this parish, spinster were married in this church by License this tenth day of June one thousand seven hundred and sixty two by me Joseph Dickenson, Rector. This marriage was solemnized between us Samuel Emery and Sarah Turner. In the presence of Henry S Turner and John Hurlbutt. They all signed.
I also found the following marriage at St Marys Stafford which may be of interest to you. I don't know if there's any connection but the name caught my eye.
Henry Turner of the parish of Castle Church in this county, gentleman and Prudence Sutton of this parish, were married in this church by License this twenty second day of December one thousand seven hundred and fifty seven by me Joseph Dickenson, Rector. This marriage was solemnized between us Henry Turner and Prudence Sutton. In the presence of John Hurlbutt and J. (can't read surname). They all signed.
I looked at the baptisms for Brewood from 1759 to 1780. There are no baptisms for John and Ann's children. There are baptisms for both Samuel and Sarah's children and John and Catherine Turner's children.
Here are Samuel and Sarah's children - all the dates are baptism dates.

April 18th 1765 Samuel son of Samuel and Sarah Emery
