[5]: 9–10 [Alfred Ernest "Alf"] Dipper is not the best man they have at Tewkesbury, for D. L. Priestley would be in the front rank if he could only afford the time to play regularly.
[28] He came into the side to replace Charles Barnett,[28] playing as an amateur in a team that consisted largely of professional players.
[2] In July 1910, Priestley made his final first class appearance against Worcestershire at the War Memorial Ground in Amblecote near Stourbridge.

[72] In March 1942, Raymond, then vice‑chancellor of the University of Birmingham, gifted money to Tewkesbury Grammar School to found two cricket prizes in memory of his brothers.
