Mariana

From Tardis Wiki, the free Doctor Who reference
You may be looking for Marianna, the Time Lady.

Mariana was the wife of Mikhail and the mother of Pris.

Mariana and her family were part of a colony ship, the Amandala, that was heading for Galaxy Eight. However, an emergency on the ship caused core damage, and in order to prevent a core rupture, the Eighth Doctor shunted the energy away. This had the effect of creating an EM pulse, which killed Mariana and everyone else on board except Mikhail. (PROSE: Reversal of Fortune)
