Biography
At the National Space Museum, Bernice Summerfield observed Stephen Hawking "deep in conversation" with Richard Dawkins and his wife. (PROSE: The Dying Days)

Resurrection
Richard and his wife eventually died and were resurrected in the City of the Saved.

In AF 291, Prof Vril pontificated to a group of guests about Richard's incorrect views on how the City of the Saved disproved Heaven. He told the guests that he had only just told Richard's wife this, and he even mentioned that it hadn't been the first time. (PROSE: Unification Theory)

Information from invalid sources
Lalla Ward was featured in the Big Finish audio adaptation of The Doomsday Contract. (NOTVALID: Tom Baker stars in John Lloyd's lost Doctor Who adventure, The Doomsday Contract)

Other matters
Whilst she wasn't named in either The Dying Days or Unification Theory, Richard Dawkins' wife is clearly intended to be Lalla Ward.

Lalla Ward's real world co-star Tom Baker was planned to make a cameo in The Dying Days, but he was ultimately cut.
