Princess Johanna Marina Eleonore of Hesse and by Rhine (Johanna Marina Eleonore Prinzessin und Landgräfin von Hessen; 20 September 1936 - 14 June 1939) was a German and Rhenish child princess, the third child and only daughter of Georg Donatus, Hereditary Grand Duke of Hesse, and Princess Cecilie of Greece and Denmark. She was orphaned at the age of fourteen months when her parents, older brothers Ludwig and Alexander and paternal grandmother Eleonore were killed in a plane crash on their way to a family wedding in London. The remains of her unnamed stillborn baby brother were also found among the wreckage. After the accident, her paternal uncle Ludwig married his bride Margaret Campbell Geddes. The couple adopted Johanna, their orphaned niece, and planned to raise her as their own daughter, but she developed meningitis and died twenty months later at the age of two and a half. Following Johanna's death, she was buried with her parents and brothers at the Rosenhöhe. Ancestry
