Saint Patrick is the patron saint of all of Ireland. Northern Ireland is only in existence as a separate entity since 1922. St. Patrick brought Christianity to all of Ireland and there are a number of places in modern day Northern Ireland that he is associated with, like Downpatrick and Slemish mountain.

Most people in the US who profess any religion profess to be Christians. There are many denominations of Christianity in the US.
Most people in Ireland practice Catholicism
in the whole world about 33% of people practice it and it is the most popular religion in the world. I am not sure where they practice it but i would assume it is in a church. It's no like they practice it in the parking lot..at least i don't think they do.
Religions do not divide Northern Ireland from the Republic of Ireland. What you are referring to is the fact that most people in the Republic of Ireland are Catholic and most people in Northern Ireland are Protestant. There are also a large amount of Protestants in the Republic of Ireland and a large amount of Catholics in Northern Ireland.
Christianity is the main one, mainly Catholic.
