Just in case the following are of any use to you.
John Turner baptised 8 Oct 1780 in Thaxted, he is one of ten children I have listed for William and Mary baptised at Thaxted 1775 to 1793.
A William Turner married Mary Freeman 22 Jun 1774 at Thaxted.
The above families are not, as far as I know, related to my Turners but I noted them in passing whilst looking for mine.
There were quite a few Turners baptised in the 1700s in both Lindsell and Elsenham.
Regards.
