They were married at St. Peter's Church, Lee, S.E. which I suspect is a suburb of London?

We know from a book held in the All Saints Church at Banstead, that George served in the Great War and was a 2nd Lieutenant in the Royal Garrison Artillery, serving in Egypt, Gallipoli and France. It also tells us that he was wounded.

Before becoming a 2nd Lieutenent in the RGA, he served in the Surrey Yeomanry and the General Service Lancers as a Lance Corporal. His medal record shows that he took part in "Theatre of War 3" from 3 April 1915 which I believe was Egypt and quite possibly Mesopotamia (Iraq), Gallipoli and Palestine.

From the The Tatler - 12 December 1951:
Famous Rugby Cubs
Streatham
As long ago as 1871 there was a Streatham Rugby Club, but no documentary evidence exists as to its fate. The present organization, one of the five oldest clubs in London, was founded in 1893 by the fusion of Thurlow Park, Lewin Rovers and Streatham Park. Three of its founder members are octo genarians; C. W. Greenhill, A. L. Goodall, the first captain, and H. T. Howard, leading players in those early days, still retain member ship of the club they helped to start on its distinguished career.
Turning over the pages of its records, one notes that of the early exponents of the Rugby game in Surrey, only Sutton, founded in 1881, and Streatham, survive the passing years.
Streatham has produced two England internationals in W. V. Butcher and P. S. Hancock, selected for all three matches in 1904, while members who have played for Surrey include C. G. Dickson, H. B. Sawday, H. R. Frisby, F. A. Stone, B. R. Knibbs, C. J. Abbott, J. A. Rowe, C. W. R. Francis, J. H. S. Howard, now the popular Club President and Treasurer of Surrey County, C. R. Williams, E. H. Lloyd and J. G.Jonas, the present captain of the club.

From The Tatler, 12 August 1953:
This edition of The Tatler gave a history of the Banstead cricket club which it said was founded in 1892. It went on to say:
This year's president is Stanley Baker, well known in Fleet Street circles, and B. R. Knibbs celebrates twenty-five years as honorary secretary this season.
