You should try the 'General Register of Lunatics in Asylum' held at The National Archives of Scotland in MC7. This covers all of Scotland and tells you name, date of admission, which asylum, date of death or discharge and patient number. With the patient number and date of admission you can then look at MC2 'Notices of Admissions by the Superintendent of the Mental Institutions' which will include a report by the admitting physician with details such as mental and physical health, age, marital status, previous place of abode, nearest relative and whether any other member of the family had been insane.

I have used these records to learn more about someone recorded in an asylum on the census when hospital records did not survive and was surprised by the great amount of detail, including the fact that this was not their first time in an asylum.

There are more details of these records in the NAS Catalogue and in 'Tracing Your Scottish Ancestors – The Official Guide'.

To find hospital records you can use the Hospital Records Database at http://www.nationalarchives.gov.uk/hospitalrecords/ which includes Scotland.

Hope that helps and you will learn more about your ancestor. Please feel free to contact me if you would like to discuss these records any further.
