From Tardis Wiki, the free Doctor Who reference
Raina Kerenskaya was a Soviet lieutenant from Kiev in 1967. She was the mother of Raine Creevy. She was planning something with Markus Creevy. She was delighted at seeing him again.
While she was pregnant with Raine, she placed the helmet of Sezhyr onto her head, causing Sezhyr to take over her body. Fortunately, she was eventually freed and went to live with Markus and Raine. (AUDIO: Thin Ice)
