Long before becoming the Pope Leo XIV, Robert Francis Prevost was simply the youngest of three siblings growing up in a Dolton home on the outskirts of Chicago, where books, education and faith formed part of daily life.
In that home there was a woman who left a deep imprint on his formation: his mother, Mildred Agnes Martínez, a librarian with Spanish and Creole roots, deeply committed to the Church and to education.
She was affectionately called Millie. She had studied at the university, worked surrounded by books, sang in her parish choir and participated in numerous community activities. Alongside her husband, Louis Marius Prevost, she built a family in which spirituality was not limited to religious celebrations, but was present in the small daily gestures of everyday life.
Mildred died in 1990, when Robert was 34 years old. He never lived to see her become a bishop, cardinal or pope. Nevertheless, her story helps illuminate part of the family and emotional universe in which the vocation of the first American pope was born.
Who Was Mildred Martínez, the Mother of Pope Leo XIV
Mildred Agnes Martínez was born on December 30, 1911, in Chicago, into a family with a rich cultural history. Her parents, Joseph Martínez and Louise Baquié, had ties to the Creole community of New Orleans, a society threaded with different cultural heritages, including Spanish, French, Caribbean and African roots.
That diversity formed part of Mildred’s family history, who grew up in Chicago with her sisters, in an environment where education and religion occupied an important place. Two of her sisters chose religious life, while she found her vocation in teaching, books and community work.
Her story also reflects the determination of a woman who decided to continue studying in adulthood, at a time when opportunities for university education for many women were more limited than today.
The Librarian Who Found in Books a Way to Teach
One of the most interesting aspects of Mildred’s life was her commitment to education. At 34 she returned to university studies and studied at DePaul University in Chicago. In 1947 she earned a degree related to librarianship, and two years later completed a master’s in Education.
Her professional trajectory was linked to different educational institutions, including Von Steuben, Mendel and Saint Mary of the Assumption schools. There she carried out her work as a librarian, a profession that allowed her to fuse two of her great interests: knowledge and the formation of new generations.
But her dedication to books also extended to religious life. Together with her husband, she helped create a library for the parish of Saint Mary, where the family actively collaborated. In that environment grew the young Robert, surrounded by a family culture that valued study, reading and the service of others.
The Home Where Robert Prevost Grew Up: Three Siblings, Education, and Shared Faith
Mildred married Louis Marius Prevost, a man of French and Italian descent who had served in the United States Navy during World War II. After his military experience, Louis dedicated his career to education. He worked as a teacher and rose to the position of school principal.
The couple had three children: Louis Martín, John Joseph and Robert Francis, born on September 14, 1955. Robert was the youngest of the siblings.
The family settled in Dolton, a town south of Chicago, where they developed a life deeply connected to the Catholic community of Saint Mary of the Assumption. The three siblings grew up taking part in parish activities, while their parents collaborated with catechesis, the organization of celebrations and various charitable initiatives.
The Prevost home was a place where school responsibilities, family traditions and religious practice coexisted. And it was precisely in that environment that Robert began to show, from a very young age, his interest in the priestly life.
Millie, the Mom Who Sang in the Choir and Devoted Her Time to the Parish
In addition to being a librarian, Mildred had an artistic side: she loved to sing and had a contralto voice. During her youth she participated in musical activities in Chicago and, over the years, continued to develop that passion as a member of her parish choir.
She also collaborated with the Altar and Rosary Society, a women’s organization devoted to supporting religious and community life. Her commitment was constant. She took part in fundraising, helped maintain parish spaces and supported various community initiatives.
Those who knew her remembered her as one of those women who were always available when the church needed help. Faith, for Mildred, was not only a personal belief. It was also a way to participate, share and build community. And that way of living spirituality was part of the education her children received.
How Mildred Martínez Influenced the Religious Vocation of Pope Leo XIV
Robert Francis Prevost expressed from a very young age his interest in religion. According to family memories shared after his election as Pope, when he was a child he even played at celebrating Mass in his home, as if he were a priest.
At 14 he entered the minor seminary of the Order of Saint Augustine, taking the first steps of a vocation that would lead him to devote his life to the Church. The influence of his parents was important in that path.
While Louis participated in religious education, Mildred transmitted her faith through daily activities, community involvement and her commitment to the parish. On several occasions, people close to the pontiff noted that Robert always valued the Christian formation he received during his childhood. That education was not only linked to religious beliefs, but also to values such as service, responsibility and solidarity.
With time, Robert continued his formation, became an Augustinian priest and carried out much of his pastoral work in Peru, a country that would come to occupy a central place in his life.
Mildred Died Without Seeing Her Son Become Pope
Mildred Martínez died on June 18, 1990, at the age of 78. At that moment, Robert Prevost was 34 and had already begun his priestly path within the Augustinian Order.
Her mother never saw him named bishop of Chiclayo, Peru, nor elevated to cardinal. She also did not witness the historic moment of May 8, 2025, when her son was chosen as Francis’s successor and took the name Leo XIV.
Her husband, Louis Marius Prevost, died in 1997. When Robert appeared for the first time on the central balcony of St. Peter’s Basilica, his parents had already passed away. However, their story was brought back to prominence: that of the father who taught and led a school, and the mother librarian who had devoted much of her life to serving their community.
The Legacy of Mildred Martínez: A Mother Present in Leo XIV’s Story
Mildred’s story allows us to learn a more intimate facet of the man who now leads the Catholic Church. Before the ecclesiastical responsibilities, before his years as a missionary and his arrival at the Vatican, there was a childhood shared with two siblings and parents deeply committed to education and faith. Mildred never knew the fate that awaited her youngest son.
But her story remained linked to that journey, not by having occupied a public place, but by the life she built and the values she transmitted.
Because, long before being Leo XIV, Robert Prevost was a boy who grew up among books, songs and a family that made faith and service to others a way of life.
