NEW UPDATE COMING:
During the Key to Time, it seems the Name of the Doctor is said by another time lord.
Armageddon Factor 'Tom Baker' meets up with another TimeLord who left around the same time as the Doctor who knew him by his actual name. Tom had to remind him he no longer goes by that name since he left. First Name Peter, I plan to watch it again to get last.... began with a Z. .....
Just thought that was interesting. 2014 01 30.
Theta Sigma -
Apparently LATER episodes with the 7th Doctor, he passed this name off as a nickname in college. Hmmm.... Read the wiki on the topic to see.
HEADS UP: Corrected another error. 20140113
A rough chart on the Doctor's many regenerations.
Also on Facebook, see page in URL.
Its actually bigger then it says on the side, will likely correct that at a later date.
Working and researching on a new graph about his time travels....
Going to take longer.
