Born's wife Hedwig (Hedi) Martha Ehrenberg (1891–1972) was a daughter of the jurist Victor Ehrenberg and Elise von Jhering (a daughter of the jurist Rudolf von Jhering). Born was survived by his wife Hedi and their children Irene, Gritli and Gustav. Singer and actress Olivia Newton-John was a daughter of Irene (1914–2003), while Gustav is the father of musician and academic Georgina Born and actor Max Born (Fellini Satyricon) who are thus also Max's grandchildren. His great-grandchildren include songwriter Brett Goldsmith, singer Tottie Goldsmith, racing car driver Emerson Newton-John, and singer Chloe Rose Lattanzi. Born helped his nephew, architect, Otto Königsberger (1908–1999) obtain commission in the Mysore State.
