Charlotte Mayfly
From Tardis Wiki, the free Doctor Who reference
Charlotte Mayfly was an amateur astronomer whose work with her brother, Jonathan, impressed Vastra.
Charlotte took Jenny Flint to the Royal Observatory where they met Neville Plumstead, whom she learnt was responsible for Jonathan's premature ageing. She was determined to help Jenny, Vastra and Strax stop him. She later applied for the job as assistant to the Astronomer Royal. (AUDIO: The Ghosts of Greenwich)
