Presidents of (at least a little) Irish descent
At least twenty-three presidents of the United States have some Irish/Northern Irish (Scotch-Irish American) ancestral origins, although the extent of this varies. For example, both of Andrew Jackson's parents were Irish born while George W. Bush has a rather distant Irish ancestry. President Kennedy had far stronger Irish origins, which fell much closer in terms of date. Also Ronald Reagan's father had some Irish Catholic ancestry, and his mother some Scots-Irish. James K. Polk also had Scots-Irish Ancestry. Only Kennedy was raised as a practicing Catholic.
