Sorry to bump an old and obscure topic, but I was looking through wedding announcements from The Times I found the marriage of Princess Luise's son Vernon. I can't help myself but post it, because it contains some (purposeful?) misinformation. The wedding took place during WWII.
The Times, Monday, Mar 29, 1943; pg. 6; Issue 49506; col B
Mr. W. V. Hope-Johnstone and Miss Cobbold
"The marriage took place on Saturday ... of Mr. William Vernon Hope-Johnstone, Grenadier Guards, only son of Mr. and Mrs. V. W. Hope-Johnstone, of Potchefstroom, South Africa..."
I could be wrong, but I wonder if the reason why he's listed as the son of a couple entirely different from his own parents, is the fact that his parents were divorced and his mother was German. Perhaps he was adopted, but I wonder if some familial "whitewashing" was happening? I imagine this might also have happened frequently during the war for anyone with foreign (adversarial) kin.
