Francisco and Jacinta were two of the three Fatima, Portugal visionaries of the Marian apparitions in 1917.
Lucia Santos, their cousin, was the 3rd visionary.
Francisco died at age 11 and Jacinta at age 10, both within 3 years of the visions. (Making them the youngest non-martyrs to be beatified in Church history. Beatified by Pope John Paul II - now St. John Paul II.)
Lucia Santos died Sister Lucia, at the age of 97 in 2005.
The speculation is that the canonization will take place on the 100th anniversary of the first apparition, which is May 13, 2017 - in Fatima.
Blessed Francisco and Jancinta - Pray for us!
