The small district of Aarle Rixtel, in the north of Holland, was made up of many families who earned their living from the land. Father Eustace's home was no different. Guilherme van Lieshout and Elizabete van den Meulenhof alternated between work and prayer in raising their eleven children.

Hubertus van Lieshout, Father Eustace's birth name, was born on the morning of November 3, 1890, and on the same day, he was taken to be baptized in the church near his home. The family was so religious that three of his sisters decided to become nuns.

As a child, Eustace read about the life of Damien de Veuster, a priest of the Congregation of the Sacred Hearts of Jesus and Mary, who had gone on a mission to an island in Hawaii where lepers were kept. The man, who would later be known as Saint Damien of Molokai, lived on the island for 16 years and died of leprosy. This example led young Hubb, as he was called at school, to decide to enter the seminary shortly before his 15th birthday.

On August 10, 1919, he was ordained a priest and became Father Eustáquio van Lieshout, ss.cc. He wanted to be a missionary like his hero, Saint Damien, and his Molokai was, therefore, Brazil.

In Brazil, he traveled through many cities, caring for the people entrusted to him, praying and blessing all who sought him out. Many people tell of miraculous cures granted by God through the intercession of Father Eustáquio, a man who truly lived his faith intensely, with all the virtues of a blessed one, and for this he was elevated to the list of the Blessed of the Church, which now anxiously awaits his canonization.
