New Orleans Remembers a Beloved Advocate, Mary Katherine Casey, Who Passed Away at 94
New Orleans, often referred to as the city of jazz, is mourning the loss of one of its longtime champions, Mary Katherine Casey, who peacefully passed away on March 26, 2025, at the age of 94. A true Texan at heart, Mary Katherine Brady was born in Houston on November 29, 1930, but always embraced her adopted city with open arms.
A Journey from Houston to New Orleans
Mary Katherine’s journey began in Houston where she attended St. Agnes Academy, graduating in 1949. Her thirst for knowledge then took her to Loyola University in New Orleans. At Loyola, her vibrant spirit shone brightly as she earned the title of Campus Queen and joined the ranks of the illustrious Cardinal Key society.
A Love Story and a Life of Service
Shortly after graduating, she met the love of her life, Thomas Casey, and their whirlwind romance led to 65 years of shared life and laughter. As her husband embarked on a successful political career in the Louisiana Legislature, Mary Katherine took on the vital role of campaign manager, effectively advocating for family values and their shared faith in the community.
Mary Katherine wasn’t just a support system for her husband; she actively volunteered at their children’s schools, including the esteemed Ursuline Academy and Jesuit High School. Her leadership even extended to the Archdiocese of New Orleans where she chaired Pre-Cana, supporting couples as they prepared for marriage.
Community Advocate and Catholic Leader
Beyond education, Mary Katherine was a stalwart advocate for many causes. She held leadership roles such as president of the Ladies Auxiliary of New Orleans Junior Chamber of Commerce and served on boards that focused on nursing care quality and the arts. Her love for New Orleans was evident in her work as a tour guide for over 20 years, sharing the city’s rich history and culture with visitors.
Her deep commitment to her faith shaped her daily life as she attended Mass regularly and mentored participants in various Catholic organizations. Mary Katherine was a cherished member of multiple parishes, including St. Rita and Holy Name of Jesus Church, and received the esteemed Order of St. Louis Medallion Award for her dedicated service.
A Legacy of Family and Love
Mary Katherine’s legacy lives on through her family. Survived by her five children—Pamela Casey Stanton, Thomas Alcade Casey, Jr., Katherine Casey Caffery, Shannon Casey Countryman, and John Brady Casey—and a large brood of 11 grandchildren and 10 great-grandchildren, her family reflects the values of compassion and kindness she instilled through her nurturing spirit.
Travel was a significant part of their family culture. Together, they explored all 50 states and ventured to over 50 countries, creating a lifetime of cherished memories.
A Final Farewell
With gratitude, the family acknowledged the tender care received from the staff at Lambeth House during her final days. They invite friends and community members to honor Mary Katherine’s vibrant life during a Funeral Mass at St. Rita Catholic Church in New Orleans on April 2, starting at noon, with visitation at 11 a.m. In lieu of flowers, they request donations be made to either The National Shrine of Our Lady of Prompt Succor or Covenant House in New Orleans, furthering the causes she cared deeply about.
