Marilyn Kroc Barg was born on October 15, 1924, in Chicago, Illinois, during a time when the city was bustling with culture and economic growth. Chicago was the place where her father, Ray Kroc, nurtured his entrepreneurial spirit, and it also became the foundation of her early years. Growing up in such an influential environment, Marilyn experienced both the energy of the big city and the familial challenges of being part of a household destined for fame.
Parents: Ray Kroc and Ethel Fleming
Marilyn’s parents, Ray Kroc and Ethel Fleming, had very different backgrounds. Ray was ambitious and driven, eventually becoming the powerhouse behind McDonald’s Corporation, while Ethel was a talented actress known in her own right. Together, they provided Marilyn with a blend of creativity, ambition, and opportunity. However, their marriage eventually ended in divorce, shaping much of Marilyn Kroc Barg’s personal story and influencing her outlook on relationships and family life.
Family Background and Early Influences
Coming from such a unique family, Marilyn’s early influences were shaped by both public recognition and private struggles. As the daughter of McDonald’s founder, she was connected to one of the greatest business stories of the 20th century, yet her own personal journey was not marked by corporate involvement. Instead, her influences came more from family traditions, personal interests, and the challenges she faced along the way.
The Kroc Family Connection
Ray Kroc’s Journey as McDonald’s Founder
To understand Marilyn Kroc Barg’s story, it is essential to explore the legacy of her father.

His vision, determination, and relentless pursuit of success made McDonald’s Corporation a global brand. For Marilyn, being Ray Kroc’s daughter meant growing up connected to a world of ambition, innovation, and business transformation, even if she did not participate directly in it.
Ethel Fleming’s Role as Mother and Actress
Ethel Fleming, Marilyn’s mother, brought a touch of Hollywood glamour to the Kroc family. As an actress, she lived in a world of creativity and performance, which likely influenced Marilyn’s early environment. The balance between Ray’s business ambitions and Ethel’s artistic background provided Marilyn with a dynamic upbringing, even though their marriage eventually ended.
The Family Dynamic During McDonald’s Rise
The family dynamic during the rise of McDonald’s was complex. While Ray Kroc focused on expanding the business, Marilyn and her mother lived more quietly.
