Like Bob says, Garlands in its original state closed - though it seems to be mushroomong behind the houses - endless blocks for physio, various mental health care etc and miles of mamagement.
Not much use to you, though!
there was a church there - you guessed - housing too, now! But actually with your dates, I think if he were buried in Carlisle it would be the cemeteries.
Do you have an address, ie abode as opposed to where he was removed from on either the deatrh certifiace or the burial record?
Have you got the full entry from the burial register?
Have you managed to check if there's a death announcement in the local papers - not too big a job if you've got the date of death?
Just a few thoughts!
