Forgive me for throwing in a couple of georgraphic snippets into this Chat.
I noticed those Jeffrey births/baptisms from "familysearch" showing places Twizel and Durham.
The quirk is that Durham was over 60 miles distant to the south. This area, including Twizel, lay within the ancient parish of Norham, And although it lay within the bounds of the county of Northumberland, it belonged to the Bishops of Durham and was regarded as part of County Durham.
The "enclaves" of Norhamshire, Islandshire and Bedlingtonshire, were collectively referred to as "North Durham".
Folk born in these areas were recorded as Durham-born, not Northumberland-born. For the 1801-1841 census, these areas are enumerated as County Durham, not as part as Northumberland.
Conveniently these enclaves reverted to the county of Northumberland in 1844. And from1851, censuses were enumerated as Northumberland.

In Old English, "twisla" was name for land that lay within a river fork. Twizel (once Twysill) lies in the junction where the River Till joins the River Tweed. (Haltwhistle in south-west Northumberland is similar example.
