Try one of the village libraries rather than a main town library, they will all have the service. Also most libraries will have a family history self help group led by one of the local studies librarians, they are doing all they can to keep people using the library resources as their jobs are at risk all across the country with internet usage at home.
Anyway, catholic Orphanages will not just crop up on ancestry itsself but you may find a useful posting a query in their forum, which i think you can do without subscribing. there are alot of sites that will be of use but mostly try this one to find the orpanage you need:
