Percival Albert Wescome Miller was born in Birkenhead in the Port Adelaide area in 1884. It seems that he was one of the young, local born men that Jock Wylde was said to have recruited and trained in the British Association game at the Hindmarsh club in 1905. Percy Miller played for both Hindmarsh and Port Adelaide between 1905 and 1912. Newspaper reports said he was a “great find”, being both “fast and tenacious”, but sometimes “too impetuous”.
He enlisted in January 1916 as a single man who worked as a labourer. As a private with the 43rd battalion he arrived in France at the end of 1916. At the battle of Messines in June 1917 he came under heavy shellfire and was hospitalized with concussion and deafness. Sent to England, Miller failed to recover and was returned to Australia and discharged in October 1917.
Percy Miller married May Collins in Adelaide in 1921. He died in 1948 aged 63.
