admission records should have been deposited at the relevent CRO probably during the mid/late 1900s and so that means they may not be complete or in good condition, as for what you can expect to find, there was a set amount of info, like name, township, age, marital status , occupation, also date of admission and whether they were sick or mentally ill. there are always the census pages that list inmates, most workhouses kept men and women seperate and children stayed with the mother but could also have been a[pprenticed out by the overseers, it depends on the era.
