What does the census tell me?
Irish Genealogy calls the 1901 and 1911 census a good place to start, saying it is free, intuitive and has images of all the original census forms. They give a snapshot of an entire household, with ages, occupations and counties of birth, and in 1911 the number of years married. Source: Irish Genealogy: how to approach family research.
