Hi Rob and everyone else on here.
I have managed to find the following marriage information and hope its the one you were after:
St Marys & St Chad's, Brewood,
The said John Turner of this parish and Catherine Tagg of this parish were married in this Church by Banns this ninetinth day of October in the year one thoufand seven hundred and sixty by me Thomas (can't read surname) minister. This marriage was folemnized between us John Turner - his mark and Catherine Tagg - her mark. In the prefence of John Simfon (not sure on surname) - signed and John Yates - his mark.
No other details given. I also had time to recheck the burials and found the following for you, both at Brewood:
1788 Jan 2nd , Jno Turner from (looks like 'Lane End' but not sure).
1776 Sep 28, Walter Turner
Also found this baptism, it may be the John and Catherine from the above marriage?:
1776 May 9, John, son of John & Catherine Turner
Hope I have the correct people.
