William James Manning was a Vice President of the Aliens and documented in the 1912/13 handbook but there is no record of him playing rugby.

At the AGM held at Elm Bank, Oakfield on the 27^th May 1913 his name struck off the list of members, perhaps he resigned due to leaving the city for an appointment in London.

Born around 1879 in Leeds he became Schoolmaster at St Michael's RC School in York Street and married Alice Nuttall in September 1899.

For WW1 James Manning joined up in the King's Liverpool Regiment, then on to the Royal Fusiliers and  London Regiment. According to NUT Records he won the DCM. (Can't be ratified as the award went to a Scots Guard with the same name). He was invalided out of the war with a gun shot wound to the back and head, receiving the Silver War Badge.
