Carolyn McConnell
From Tardis Wiki, the free Doctor Who reference
Carolyn McConnell was a human living in San Francisco. She met the Eighth Doctor and Sam Jones in 1976 when Carolyn was a pre-med student. After a vampire encounter, the Doctor gave Carolyn a hypercube to contact him if she had more problems with them. She did so in 1997, by which time she has become a medical researcher.

When the Eighth Doctor contemplated living in early 2000s San Francisco, he reflected that he could invite Carolyn and James Court over for dinner. (PROSE: Unnatural History)
