In his book “De Roberto a León” (“From Robert to Leo”) published by Editorial Mensajero, Armando Lovera, a native of Iquitos, Peru, provides data and insights that illuminate the maternal influence in the life of the pope.

1. Two of Mildredʼs sisters embraced religious life

A testament to the importance of the Catholic faith in Mildred’s family is that two of her sisters, Louise and Hilda, decided to consecrate their lives to God by joining religious congregations.

Louise Eugenie, born in 1903 in New Orleans, was the first to take this step: at the age of 19, she entered the Sisters of Mercy. Years later, in 1928 at the age of 21, Hilda followed in her footsteps by professing vows in the Sisters of Charity of the Blessed Virgin Mary.

2. Mildred lost her father as a young teen

Mildred’s childhood was marked by the loss of her father, Joseph Martinez, who died on July 31, 1926, when she was just 14 years old. His death left her mother, Louise, a widow who was then compelled to enter the workforce. Mildredʼs mother, the popeʼs maternal grandmother, found employment at a nut and candy factory, where she worked as a taster, evaluating the quality of the products.

At the same time, Mildredʼs older sisters, Irma and Margaret, also assumed responsibility for the family’s financial support, thereby enabling the family to stay afloat during a time of exceptional hardship.

3. She was educated to be an independent woman

In the 1920s, Mildred began her studies at Immaculata High School, a Catholic girls’ school founded by the congregation to which Hilda belonged.

The education she received was not limited to academics. The institution sought to prepare women capable of navigating public and professional life, fostering both intellectual development and Christian values, with a clear commitment to women’s independence.

4. She had a life dedicated to books and education

At the age of 27, Mildred began working at a public library, performing administrative tasks. Three years later, she enrolled at DePaul University to study library science. She completed a postgraduate degree in education in 1949.

Her passion for books was not limited to the professional sphere. For years, she volunteered at the parish library: She organized the collections, cataloged books, and arranged public readings to promote culture.

5. She was a sacred music singer and distinguished soloist

Mildred possessed a deep and powerful contralto voice. This was no mere hobby: she performed as a soloist in numerous sacred music concerts.

In 1941, Mildred even appeared at the prestigious Chicagoland Music Festival, held at Soldier Field before an audience of over 100,000 people. Her repertoire centered on sacred music, and among her performances, her rendition of the “Ave Maria,” a demanding piece even for professionals, stood out in particular.

6. The first time her future husband met her family nearly ended in disaster

The family history also yielded some singular anecdotes. Mildred met Louis, who would become her husband and the father of the future pope, at DePaul University in 1948. However, his first meeting with her family nearly ended in disaster.

Invited to their home, Louis arrived feeling unwell; he took some medication and shortly thereafter fainted in front of everyone. Joking around, one of the sisters declared that he wouldnʼt be back. But he did return. Months later, on Jan. 25, 1949, they were married at Holy Name Cathedral in Chicago and began their life together in Dolton, Illinois.

7. Her electric organ ended up in Trujillo, Peru

In addition to singing, Mildred played the piano and actively participated in her parishʼs music ministry.

Years later, her electric organ was transported by her son, then-Father Robert Prevost, some 3,500 miles to the Augustinian formation house in Trujillo, the city where he worked from 1988 to 1999.

8. Mildred played a decisive role in her sonʼs vocation

Mildred was a pillar in the spiritual life of the Prevost family, which lived parish life as if it were an extension of their own home. Their home served as a regular gathering place for priest friends, whom she would often invite over for a meal. These gatherings, characterized by simplicity and warmth, helped to kindle in the heart of the youngest of her three sons his desire to be like them.
