Ellis Island opened on January 1, 1892, and the first immigrant to be welcomed was Annie Moore, who was either a 15 or 17 year-old Catholic girl from Ireland. She and her younger brothers traveled over from Cobh, County Cork to join their parents who were already in American. Moore went on to marry a German and have a bunch of kids in New York City, contrary to some popular myths. Twelve million immigrants passed through Ellis Island during its 62 years of service, most of them from historically Catholic countries. Ellis Island was the first central immigration point set up by the federal government after nearly 100 years of immigration being controlled by the states.

Mother Benedict Duss hid from the Nazis in her French Benedictine monastery during World War II. After General Patton's Third Army liberated her abbey she pledged to return to the United States to establish a Benedictine monastery to pray for and bless her homeland. Through the assistance of two future popes — both of whom would eventually be canonized — and a number of other providential happenstances, the Abbey of Regina Laudis was finally established in Bethlehem, Connecticut. The story of the founding eventually became the basis for the acclaimed movie Come To The Stable, which was nominated for eight Oscars, including for the screenplay written by Clare Booth Luce. Regina Laudis has been the home of Mother Dolores Hart since she left a budding Hollywood acting career in the 1960s, and it was the place where the actress Patricia Neal found solace and healing after her tumultuous life.

Father Aloysius Schmitt was a Navy Chaplain assigned to the USS Oklahoma at the outset of World War II. He had just finished the 7 a.m. Mass on the Second Sunday of Advent when the first torpedoes from the surprise Japanese attack struck the ship. He aided men to escape, at the cost of his own life during the attack on Pearl Harbor. He was the first chaplain to die in World War II.
