Thanks, Pete - that's very helpful.  I've come across this kind of thing before.  It's probably something to do with how districts were administered in the days when registration was first set up, & it's never been changed - historically interesting, but frustrating for present-day research!
When researching my late wife's family, all of whom lived in the Clayton/Great Horton part of Bradford, I found all BMDs were recorded as "North Bierley".  This puzzled me, as I'd never heard of it when I lived in Bradford for 3 years. So I looked at an OS map.  There's no such place as North Bierley!  There IS a Bierley and an East Bierley - neither of which are anywhere near Clayton & Gt Horton!   It's just a minor suburb, but is (or was) important to the registrars!

Hi, Sharon
I'm a bit behind the times here, but I've just spotted your queries re a possible Atcham Asylum.  I've just learnt that an ancestor of mine died "in an asylum" at Shrewsbury in 1889.  Ancestry UK's death records actually show him as dying at "Atcham".
So did you ever find out whether there was what nowadays we'd call a mental hospital at Shrewsbury ?  (He was living in Shrewsbury for the 1881 Census, & still presumably OK at the time)
