Info from Anne Scott, a friend of Vivian's in South Africa:
Major Vivian Sheppard Bazalgette (Retd. The Kings Own. Definitely born April 20 he shared a birthday with Adolf Hitler. Am unsure about year of birth. We always thought he was Sir Joseph Bazalgette's grandson. Vivian died in 1993 in KwaZulu/Natal, South Africa. He and his second wife Joan were childless. They became great family friends; Joan was Godmother to my brother Mark etc. I inherited a box crammed with Vivian's medals and other military memorabilia. All diaries and documentation have been lost.
