Servant of God Auguste Robert "Nonco" Pelafigue was born on January 10, 1888, in Beaucens, France, near Lourdes. At the age of one, his family emigrated to the United States, settling in the French-speaking community of Arnaudville, Louisiana. Embracing his new home, Pelafigue pursued education and graduated from the Louisiana State Normal School in Natchitoches, preparing for a career in teaching. During this period, he became a member of the Apostleship of Prayer League of the Sacred Heart, an organization dedicated to promoting devotion to the Sacred Heart of Jesus and praying for the intentions of the Pope.

Known affectionately as "Nonco," a term derived from the French word for "uncle," Pelafigue dedicated his life to education and faith. He began his teaching career in public schools in Krotz Springs and Coteau Rodaire before joining the faculty of Little Flower Catholic School in Arnaudville in 1949, where he was the sole male teacher among the Marianite Sisters of the Holy Cross. Beyond the classroom, Nonco was renowned for his unwavering devotion to the Sacred Heart of Jesus and the Blessed Virgin Mary. He organized the League of the Sacred Heart in his community, enlisting approximately 1,200 members and 100 promoters. Demonstrating his commitment, he traversed the rural roads on foot, distributing monthly leaflets, visiting the sick, and offering spiritual support, often declining offers of transportation as a form of personal penance.

In recognition of his tireless service, Pope Pius XII awarded Nonco the Pro Ecclesia et Pontifice medal in 1953, honoring his distinguished contributions to the Church. He continued his apostolic work until his passing on June 6, 1977, which notably coincided with the Solemnity of the Sacred Heart of Jesus that year. His legacy of humility, devotion, and evangelization has endured, leading to the official opening of his cause for beatification and canonization by the Diocese of Lafayette on January 11, 2020.
