What happened September 1921 AD

Shortly after Philip's birth, his maternal grandfather Prince Louis of Battenberg, then known as Louis Mountbatten, Marquess of Milford Haven, died in London. Louis was a naturalized British subject who, after a career in the Royal Navy, had renounced his German titles and adopted the surname Mountbatten—an Anglicised version of Battenberg—during the First World War, owing to anti-German sentiment in Britain. After visiting London for his grandfather's memorial service, Philip and his mother returned to Greece, where Prince Andrew had remained to command a Greek Army division embroiled in the Greco-Turkish War.

In 1921, Wong received her first screen credit for Bits of Life, the first anthology film, in which she played the wife of Lon Chaney's character, Toy Ling, in a segment entitled "Hop".
