I should have said that the Garlands , or more properly, The Cumberland and Westmorland Mental Asylum, maintained its own death register and this may well be available for consultation.
At one time low risk patients could book in and pay for their care in a sheltered environment and call it their home. Some would take a suite of rooms and would have their own staff of maids, butler etc.
This was not common at the Garlands but at the Creighton Royal in Dumfries, 35 miles away, the hospital was noted for having houses built within the grounds to take care of the "idiot" offspring of the nobility and some of the houses were small mansions with butler, housekepper, maids, footmen, gardeners etc. In these circumstances, the inmate could well have been classifed as occupier or perhaps the housekeeper could be so classed.
