I became interested in this topic after finding my 2G-Grandmother (Browne-2258) spent the last 20 years of her life in this institution. It has an interesting 150+ year history of treating close to 15000 patients. I have linked a couple of the many articles available about it.
I have begun transcribing the census records. 1871 and 1881 are complete. 1891-1821 have been found but not begun. Any help in transcribing these records would be greatly appreciated.
