William Chesterton

Major William "Bill" Chesterton was the paternal great-grandfather of the First Doctor's companion Ian Chesterton. His father was a drunkard and a gambler who habitually slept with prostitutes.

In 1860, Major Chesterton was a member of a Hussar company in Jaipur, India. By 1865, he had been transferred to China. He bore a striking resemblance to his great-grandson, leading Ian to mistakenly believe that his ancestor was his future self who had been lost in time.

By 1890, Major Chesterton had retired to England, where he translated Mountains and Sunsets by Ho Lin Chung into English. (PROSE: The Eleventh Tiger)
