I read this astonishing bit of information in the book, "The Royals" by Kitty Kelley.
I quote, "It was Lord Stamfordham who received the unenviable job of telling King George V about D. H. Lawrence, who had been hounded into hiding because he married a German woman. The once revered writer had married the sister of German military aviator Baron
Manfred von Richthofen, the legendary Red Baron, credited with shooting down eighty Allied planes during World War I. After their wedding, Lawrence and his bride, Frieda, were forced by public hostility to seek refuge in the English countryside, where they hid in barns like animals.
