Info Re Sarah Tarry C1750 of Stoke Bruerne Northamptonshire England

I am researching the TARRY family and have hit the buffers at Sarah TARRY aka Sarah of Stoke. Sarah was unmarried when she gave birth to a son John TARRY in 1770 and this may contribute to the reason as to why I cannot seem to identify any ancestors of Sarah.

If any one has information on Sarah and her immediate family I would be very interested.
