Francisco de Jesus Marto (11 June 1908 – 4 April 1919) and Jacinta de Jesus Marto (5 March 1910[1] – 20 February 1920)[2] were siblings from Aljustrel, a small hamlet near Fátima, Portugal, who, with their cousin Lúcia dos Santos (1907–2005), reportedly witnessed three apparitions of the Angel of Peace in 1916, and several apparitions of the Blessed Virgin Mary at Cova da Iria in 1917.
[4] According to the memoirs of their cousin Sister Lúcia, Francisco had a placid disposition, was somewhat musically inclined, and liked to be by himself to think.
[6] The Congregation for the Causes of Saints, in the report that confirmed Jacinta as beatified, observed that she seemed to have an "insatiable hunger for immolation.
[8] The brother and sister, who tended to their families' sheep with their cousin Lúcia in the fields of Fátima, Portugal, reported seeing several apparitions of an angel in 1916.
[9] During the first apparition, the children said Mary asked them to pray the Rosary and to make sacrifices, offering them for the conversion of sinners.
Both lingered for many months, insisting on walking to church to make Eucharistic devotions and prostrating themselves to pray for hours, kneeling with their heads on the ground as they said the angel had instructed them to do.
Her condition steadily worsened and, in an attempt to transfer her to the children's hospital in Lisbon, Queen Stephanie's Hospital (which at the time only allowed for children from the city to be treated there), she was moved first to the care of the small Orphanage of Our Lady of Miracles, in the Lisbon neighbourhood of Estrela.
On 19 February 1920, Jacinta asked the hospital chaplain who heard her confession to bring her Holy Communion and administer Extreme Unction because she was going to die "the next night".
[11] In 1920, shortly before her death at age nine, Jacinta Marto reportedly discussed the Alliance of the Hearts of Jesus and Mary with a then 12-year-old Lúcia dos Santos and said: When you are to say this, don't go and hide.
[16] In 1937 Pope Pius XI decided that causes for minors should not be accepted as they could not fully understand heroic virtue or practice it repeatedly, both of which are essential for canonization.
[23] In the 2022 visual novel Anonymous;Code, The Holy Office 513, a powerful organisation within the Catholic Church,[citation needed] tries to create Clones of Francisco and Jacinta as well as Lúcia dos Santos by planting their memories into artificial brains.
