Teresa was adamant that James referred to her as Tracy and NOT Teresa:
Tracy: Teresa was a saint. I'm known as Tracy.
James: Well, Tracy, next time.
James Bond also corrects her father when he refers to her as Teresa:
Draco: I am also Teresa's father.
Draco: Yes, Tracy. Tracy.
The last thing that James Bond tells Tracy is that "We have all the time in the world" at the end of On Her Majesty's Secret Service.
James Bond is seen laying flowers on her tombstone in the film For Your Eyes Only.
Teresa Bond's tombstone is a personal sentiment by James Bond to her. The tombstone is sure to say "Beloved wife of James Bond" as well as the phrase "We have all the time in the world".
Since James Bond always referred to her as Tracy and she preferred that name, is there any evidence or reference from any Bond film on why the tombstone would read Teresa Bond rather than Tracy Bond?
