Ok, I'm fairly sure I know this, although I haven't been able to confirm the Zingiber (the botanical name for ginger).
Is the fifth on Robert Falcon Scott and they failed to be the first to the South Pole?
Birdie is Henry Bowers,
Taff is Edgar Evans
Titus is Lawrence Oates
Zingiber is Edward Wilson?
(I have nicknames for him as being Billy, Ted and Uncle Billy)
Scott seems to have had a ton of nicknames including: The Boss, Con, Old Mooney, The Owner, Ignotus, Juxta and Truegg.
