In Gumiel del Mercado, within the province of Burgos and Diocese of Osma, Eusebio de las Heras was born on December 16, 1913. He was baptized five days later in the parish Church of St. Peter the Apostle, a mission Church of Santa Maria Maggiore. He receive the Sacrament of Confirmation in La Aguilera, Burgos, on May 14, 1914, from the Bishop of Jaca, on the occasion of a pastoral visit to San Pedro Regalado.
His parents were Don Zechariah de las Heras and Victoria Izquierdo, which had a large family. He began his studies in the village school and like all the other children in the region would receive his Christian doctrine in the local parish or at home. His missionary vocation began surfacing when he was attracted by the preaching of the Claretian Missionaries of Aranda de Duero, specifically Father Ignacio Azurmendi. Following the example of Blesseds Antolin Calvo Calvo and Jose Figuero Beltrán, both martyrs in Barbastro, he decided to enter the Postulancy of Alagon, in the summer of 1926.
In the city of Zaragoza, he began studies of the Humanities and continued with his studies in Cervera in the summer of 1928. Two years later he moved to Vic to begin the Novitiate. He started the test year of dicipline, prayer and studies. At the end, he made his First Profession on August 15, 1931, which is the feast of the Assumption of Our Lady.
Before the end of August, he joined his companions and went to Solsona to begin the study of Philosophy. After completing the Philosophy program, he would began studies in Theology. In September 1935, he continued his studies in Theology at Cervera.
He would collaborate with other students in publishing articles in the weekly news flier La Fiesta Santificada. He had dreams of being a missionary priest, but feared that everything would be delayed because of the required military service. In reality, everything was cut short because of the Marxist Revolution.
Qualities: He was a talent student and appreciated because of his good behavior. He was fervent, docile and obedient. His Prefects believed he would be good religious.
In effect, just as he was finishing the courses of 1935-1936, on July 21, 1936, the whole community was forced to leave the house and seek refuge outside of the city limits of Cervera. The failed trip to Solsona was due to the actions of the Revolutionary Committee of Tora. So the group moved on to San Ramon, to the Mercedarian Convent. Two days later, he would join others students who traveled Mas Claret. As it happened to many other Claretians, he was shot on October 19, 1936.
