The specter known as the "White Lady" since she was always known to have worn light coloured clothing, was a deaf mute named Sophia Wyatt. Sophia an adorent fan of Lord Byron had moved to a farm near Newstead Abbey. Thomas Wildman had bought Newstead from Byron in 1817, and when he and his wife learned of Sophia's love of Byron's work they allowed her to walk the grounds of their home whenever she pleased. When the relative that financially supported her died, she earnestly set out to contact another of her relatives that had emigrated to America.

She wrote to the Wildmans informing them of her intentions, and on hearing of her plight they attempted to send word that they would provide a home for her on the grounds of Newstead for the rest of her life. Having already left on her journey, they sent a horseman to stop the coach and return Sophia to Newstead.

He found her sooner than expected. In the Market Square, Sophia had walked into the path of a horse and cart, and being deaf had not heard the warning screams of the driver. She did however return to Newstead, but in spirit. She has been seen by visitors glide out of a wall, move across the room and disappear into the wall on the opposite side, as well as her favourite haunt along the garden paths.
