Martha Tyler
From Tardis Wiki, the free Doctor Who reference
Martha Tyler was an old woman who lived in the 1970s. She was a practicing white witch and could read people's fortunes. This might have meant that she had psychic powers. She was the cook at the Fetch Priory but after a body was found she could not work there as the owner Dr. Fendelman. She helped her grandson, Leela and the Doctor to defeat the Fendahl. She later escaped from the Priory with her grandson and Adam Colby as it exploded. (DW: Image of the Fendahl)
Behind the scenes
Martha Tyler has by chance names of two of the Doctor's former companions. Rose Tyler and Martha Jones, both of which were companions of the Tenth Doctor.
