Team pictures of any era do not always include the groundsman but Harry Greenaway is featured and named in the photograph taken ahead of the 1912/13 season when he is likely to have been in his mid-thirties suggesting it is plausible that he doubled up as groundsman and player.

Harry Greenway continues to be named as groundsman in various pictures and reports throughout the inter-war period and into the 1950s. The confusing aspect to the story is him being named as an assistant trainer around the time of the Great War when this may have been Sid Greenaway. But Harry Greenaway certainly featured in the story of Dido the Seagull and the 1931 FA Cup run when it was reported that Dido, the groundsman's dog, gave his name to the club's newly-acquired winged mascot.

The Henry Arthur Greenaway who was born in 1878 died in 1959 aged eighty-one . This would place him as being in his late seventies when Sonny Clarke took over the position of groundsman in the mid-1950s. An alternative theory points to Harry and Sid Greenaway not being related which suggests the possibility of this being Henry Charles Greenway (1888-1954). If it were to be him, he would have worked as groundsman until around the time of his death at the age of sixty-six.
