Mary Jo Campbell, perhaps better known to millions as “MJ,” was more than just the mother of reality TV mogul Kris Jenner. She was the beloved matriarch of one of the most famous families in the world, the Kardashian-Jenner clan. Her life, which ended recently at the age of 91, was a tapestry woven with personal triumphs, profound losses, and an unwavering dedication to family.
Born on July 26, 1934, in Arkansas, Mary Jo’s journey was marked by resilience from a young age. While her later years placed her in the spotlight, it was her role as a mother, grandmother, and great-grandmother that defined her legacy. Her story is one of love found and lost, of raising a family through challenging times, and ultimately, of becoming the heart of a dynasty.

A Life of Three Marriages
Mary Jo Campbell’s personal life was shaped by three significant marriages. Her first foray into matrimony came at the tender age of 18, when she married her high school sweetheart. However, this youthful union was short-lived, ending after just two months when she realized marriage was not what she had imagined.
Her second marriage proved to be more consequential. She wed Robert True “Bob” Houghton in 1954. Bob was an engineer from San Diego, and together they had two daughters, Kris and Karen. Their relationship, however, was not destined to last, and the couple divorced in 1962 when Kris was just seven years old. Robert Houghton passed away in Mexico City in his 40s.

Mary Jo’s third and final marriage was to Harry Shannon, a successful American businessman. This was her longest and most stable relationship. They enjoyed four decades together, and Harry became a beloved father figure to her daughters. Tragically, their time together was cut short when Harry died in 2003 from complications related to a car crash. His death was a devastating blow to the family.
Her Children and Expanding Family
Mary Jo’s most cherished accomplishment was her family, particularly her two daughters. With her second husband, Robert Houghton, she had Kris Jenner (born in 1955) and Karen Houghton. While Kris became a global celebrity and “momager” to her own famous kids, Karen preferred a life away from the public eye. Tragically, Karen passed away in March 2024 at the age of 65.

Through her daughter Kris, Mary Jo’s legacy expanded exponentially. She became the proud grandmother of Kris’s six children: Kourtney, Kim, Khloé, and Rob Kardashian, as well as Kendall and Kylie Jenner. Her family grew further with numerous great-grandchildren, including Mason, Penelope, and Reign Disick, North, Saint, Chicago, and Psalm West, True and Tatum Thompson, and Stormi Webster.
Ultimately, Mary Jo Campbell’s life was a testament to the power of family. Her daughter Kris captured this sentiment perfectly in her tribute, stating, “My mom was the heart of our family”. She was a constant presence on Keeping Up with the Kardashians, endearing herself to fans with her sharp wit and sage advice. Mary Jo “MJ” Campbell leaves behind a sprawling, loving family that will forever be shaped by her strength, love, and the values she instilled in them.
