In the latest edition of the IOMFHS magazine there is an interesting article on the above subject.
In this article it states that "there are lists of inmates and their ages in each year's reports".
My 3 x great grandfather, Thomas Collister was an inmate there in the 1871 cenus.
Can anybody advise who I need to contact to obtain the information that, I assume, is held on Thomas?

Many thanks - Allen Blakeley (IOMFHS, MLFHS)
