Arthur Lewis was Paymaster Midshipman on HMS Cairo accompanying the Prince of Wales on his visit to Hong Kong in 1922. It's possible that he and Evelyn Warren met at the ball given in the Prince's honour at Government House. Their son has a photo of them both at Deepwater Bay. It is further possible that Charles Warren had made it a condition of Evelyn inheriting that she not marry until she was twenty-five. In any case they did not marry until 30 March 1927 after a 5-year engagement. There may also have been a financial advantage on Lewis's side for delaying his marriage. I don't know what the Navy rules were at the time. When Evelyn returned to England after the death of her father, Charles Warren, in 1923, I know that she stayed with Arthur Lewis's parents for some time before their marriage, having no family home of her own in England. Her son has a photo of her with them.
