Her mother, Ethel Fleming, was Ray Kroc’s first wife. Ray and Ethel married in 1922, and Marilyn was born as their only child two years later in 1924. The family’s early years were marked by financial instability as Ray pursued various business ideas. Ethel was a steady presence in Marilyn’s life during those formative years, providing the kind of emotional grounding that Marilyn would carry into her adult life.
Ray Kroc eventually divorced Ethel Fleming and went on to marry two more times first to Jane Dobbins Green in 1957, and then famously to Joan Beverly Mansfield (better known as Joan Kroc) in 1969. Joan Kroc herself went on to become one of America’s most celebrated philanthropists, donating billions of dollars to causes ranging from nuclear disarmament to public broadcasting.
The Kroc family history is one of the most fascinating in American business culture a story of ambition, reinvention, and ultimately, generosity. Marilyn inherited the philanthropic spirit that would later define the entire Kroc family’s public legacy.

Marilyn Kroc Barg Cause of Death
The cause of death for Marilyn Kroc, Barg has been documented as complications related to diabetes. Diabetes, particularly in the early 1970s, was a far more difficult condition to manage than it is today. Medical science in that era had not yet developed the sophisticated monitoring tools, insulin therapies, and dietary management protocols that are now standard practice in diabetes care.
Diabetes is a metabolic condition in which the body either does not produce enough insulin or cannot effectively use the insulin it produces, leading to dangerously high blood sugar levels over time. Chronic complications of the disease include cardiovascular damage, kidney failure, neurological issues, and other life-threatening conditions all of which were harder to mitigate in 1973 than they are in 2026.
The diabetes cause of death in 1973 that claimed Marilyn’s life was, sadly, not an uncommon tragedy for that generation. Many Americans of that era succumbed to diabetes-related complications that are now considered manageable with modern medicine. Her death served as a painful reminder of the medical limitations of her time and the importance of ongoing research and development in chronic disease management.
