WHO FAMILY TREE?

 

This genealogy diagram covers the basics, although the jury is still out on the Time Lord played by Claire Bloom.  (Personally, I do believe that she was the Doctor's mother.)

One day I hope the family lineage backstory for "Susan Foreman"* will finally be revealed.  And it would be proper for it to happen while we still have Carole Ann Ford among us. 

Also, the Doctor's marriages to Marilyn Monroe, Elizabeth Regina, and the Warrior Queen of Felooth should also be included, even if there was no offspring.

* O'Bservation - Susan must have had a Gallifreyan name as well, don't you think?
