Vanessa Moretti
From Tardis Wiki, the free Doctor Who reference
Vanessa Moretti was the 16 year old daughter of Salvatorio Moretti, who invented the GENIEs in the 24th century. Not knowing one was near her, she wished she could have lived "back then". Hearing this, the GENIE transported her from 2375 to 2nd century Rome. The Tenth Doctor and Rose met her there in 120 AD. They brought her back to her home time before the GENIE was invented, telling her to convince her father never to create it. (PROSE: The Stone Rose)
