It extended to almost everything. Try getting a job in Dublin at that time if you were a protestant etc etc.
Guiness was a London Company that moved to Dublin for tax reasons. The entire family converted to Catholicism.
In fairness the reverse was true in n.ireland. Thus, for example, a body had to be set up to ensure that catholics there got a fair shake in the housing market.
