Button Sahib
John Paul Warburton, The Controller of Devils. John Paul was born Jan Dad Khan and was said to be the son of Shah Jahan Begum's first husband Sirdar Faiz Talab Khan a high official of Amir Dost Mohammad,. However the Amir fled from Kabul with a large retinue at the beginning of August 1839, a week before the British arrived there, and more than a year before John Paul was born, so he is almost certainly the son of the The Begum's second husband, Colonel Robert Warburton.

The Station at Warburton, Punjab
The station at Warburton in the Punjab. The town was built on a piece of land granted to John Paul by the Indian Government, probably around the time of George V's Coronation Durbar in 1911. 
John Warburton, who took the three photos of Warburton Station whilst in the Punjab on business, made clever use of the station name to introduce a presentation.

I’m reading “Eighteen Years in the Khyber”. I first heard about it while reading Gen. Bindon Blood’s bio, ” Four Score Years and Ten”; not that the Khyber book is mentioned in Blood’s book, but I have an interest in many stories that have to do with the Victorian age. Such adventures must not be allowed to be lost in time.
Just thought you would like to hear it.
My wife and I live in New York City.
