On the 100th anniversary of the Marian apparitions at Fatima, Pope Francis canonized two of the three visionaries to whom Mary appeared in 1917, just before the end of World War I. The two siblings, just seven and nine-years-old at the time of the apparitions, died within a few years of the events during an outbreak of influenza. Their cousin, Lucia, also experienced the visions. She lived out her years as a religious sister and died in 2005. The Church recognized the apparitions as authentic in 1930.
