She married Helmut Wilhelmi in 1943.[3] They had three children, all of whom were active in the family business. Her son Raimund Wilhelmi and his wife Francoise Wihlemi de Toledo managed the clinic in Überlingen. Maria's five grandchildren also became involved in the clinics.[4] In February 2019, Leonard Wilhelmi, Maria's grandson, became manager of the Buchinger Wilhelmi clinic in Überlingen.
