In 1937, Victoria's brother, Ernest Louis, died and soon afterwards her widowed sister-in-law, nephew, granddaughter and two of her great-grandchildren all died in an air crash at Ostend. Victoria's granddaughter, Princess Cecilie of Greece and Denmark, had married Victoria's nephew (Ernest Louis's son), George Donatus of Hesse. They and their two young sons, Louis and Alexander, were all killed. Cecilie's youngest child, Johanna, who was not on the plane, was adopted by her uncle Prince Louis of Hesse and by Rhine but the little girl only survived her parents and older brothers by eighteen months, dying in 1939 of meningitis.
