These are the 51 Blessed Missionary Sons of the Immaculate Heart of Mary (Claretians) killed in hatred of the faith in August 1936. The all belonged to the Community of Barbastro, a large community, composed of 60 persons, dedicated to the formation of the missionaries; it was a Seminary of the Congregation.
Nine were priests who had charges of responsibility in the house and in the Seminary. Of the 12 Brothers of the community, only 5 received the palm of martyrdom, because they did not kill the elderly nor those that were very sick.
The rest of the community (39) were seminarians who were in the last years of theology. One was a subdeacon and 11 had received minor Orders. Two Argentinians were saved from death: they were freed at the last minute because they were foreigners. Only 9 of these martyrs were over 25 years old; 36 of them had not reached that age, and three were only 21 years old.
