Early Life and Family Background
Marilyn Janet Lynn Kroc Barg was born on October 15, 1924, in Chicago, Illinois, as the only child of Ray Kroc and his first wife, Ethel Janet Fleming. Growing up in Chicago during the early 20th century, Marilyn experienced a childhood that was both modest and full of love. Her father worked hard in various jobs before his success with McDonald’s, and her mother, who had once been an actress in silent films, devoted herself to raising their daughter.
Despite their later wealth, Marilyn’s early years were simple, and she learned important values like honesty, humility, and compassion. Her parents instilled in her the belief that helping others is one of life’s greatest responsibilities, a lesson she carried throughout her life.
Father – Ray Kroc
Ray Kroc, Marilyn’s father, was born on October 5, 1902, in Oak Park, Illinois. He was a hardworking and determined man who built McDonald’s into a global restaurant empire. Before his success, he worked many jobs, including as a milkshake machine salesman, pianist, and paper cup distributor. His big break came when he discovered the McDonald brothers’ restaurant in California. Seeing the potential in their idea, Ray bought the franchise rights and turned it into one of the most recognized fast-food brands in history.
His business vision changed how the world eats and created thousands of job opportunities worldwide. While Ray was known for his determination and innovation, Marilyn inherited his discipline and drive but chose a more compassionate path—devoting herself to charity rather than business.

Marilyn’s mother, Ethel Janet Fleming, was born in Ohio in 1890 and was known for her elegance, beauty, and gentle personality. Before marrying Ray Kroc, she was an actress who appeared in several silent films during the early 1900s. After her marriage to Ray in 1922, she left acting to focus on her home and family. Ethel played a vital role in shaping Marilyn’s character, teaching her the importance of empathy and kindness. She believed in living with grace and generosity, and these values had a lasting impact on Marilyn. Ethel and Ray divorced in 1961, and Ethel passed away in 1965.
