Princess Sophie of Greece & Denmark and Prince George William of Hanover
On April 23, 1946 Princess Sophie married Prince George William of Hanover in Salem, Baden of Germany. Sophie was the youngest daughter of Prince Andrew of Greece and Denmark and Princess Alice of Battenberg.
I agree When Princess Sophie married her first husband, it was within a few years that her three older sisters got married. At the time no one would have considered any of the Princesses becoming widowed.
Prince Philip attended the second marriage of his sister Princess Sophie at Salem in Baden.
He had not seen Sophie since before the start of the Second World War and she had remained in Germany throughout.
