Clemency Eddison

Lady Clemency Eddison was a minor member of the British aristocracy whom the Tenth Doctor and Donna met in 1926. An avid reader of Agatha Christie novels, she was the wife of Hugh Curbishley and the mother of Roger Curbishley. She fell in love with a Vespiform in human guise in India in 1886. The relationship resulted in an out-of-wedlock pregnancy. Before the child could be born, however, the father was drowned in the monsoons of 1886 when the Jumna River overflowed its banks. She returned home and hid herself away in a locked room during the pregnancy, claiming it was because she'd had malaria.

After the child was born she gave it to an orphanage. She later encountered this child forty years later, by which time he was known as Reverend Arnold Golightly and had discovered his Vespiform heritage.

Only her faithful servant, Chandrakala, knew of the pregnancy. (DW: The Unicorn and the Wasp)
