He was known to friends and family as Bim. It is unknown where this nickname derives from. It has been suggested that he was engaged at one point to Nancy Cunard. That this is untrue has been confirmed by two reliable sources: Colin Tennant, 3rd Baron Glenconner, who responded to this question by letter, and Lois Gordon, Nancy Cunard's biographer, who, in her extensive research, never came across any hint of such an alliance.
Bim Tennant is buried in France at Guillemont Road Communal Cemetery close to his friend Raymond Asquith who was killed the week before.
