On September 27th (1921) we (Russell and Dora) were married, having succeeded in hurrying up the King's Proctor, though this required that I should swear by Almighty God on Charing Cross platform that Dora was the woman with whom I had committed the official adultery. On November 16th, my son John was born, and from that moment my children were for many years my main interest in life.
