Hi Myra According to the Hospital Records Database at http://www.nationalarchives.gov.uk/hospitalrecords/search.asp, Colney Hatch patient admission and discharge registers, 1851-1985, are held at the London Metropolitan Archives. Jill Staines, Middx Is there somewhere online where there might be lists of inmates or of those who died there? asks she hopefully. I was just hoping there might be more information I can get from somewhere.
