Hexhamshire
That's a new one on me!
I’m getting a bit off topic here. The Archbishop (of York’s) Peculiar of Hexhamshire consisted of the (large) Parish of Hexham with Whitley, Allendale with the Chapelries of West Allen, Allenheads and Ninebanks, and St John Lee with the Chapelries of Bingfield and St Oswald in Lee.
It remained in the Diocese of York until 1837 when it was integrated into the Diocese of Durham.
It became part of the Diocese of Newcastle when that diocese was created in 1882.
The fact that it has been in three dioceses is the reason that records can be found in different diocesan archives including York and Durham.
Hexhamshire today is more usually called ‘The Shire’ and consists of a thinly populated but beautiful area to the south of Hexham.
