William Thomas Amor was born at Five Dock, Sydney, on 5 January 1891 to Charles and Jane Amor. He served on several ships with the Royal Navy between 2 April 1909 and 4 May 1911, including HMS Powerful.

Amor first enlisted in the Australian Imperial Force on 9 April 1915 but was discharged on 12 July 1915 with the comment "unlikely to become efficient". He was 24 years old when he enlisted again, about 12 months later, on 15 May 1916, giving his occupation as a "house man". On 7 October 1916 he left behind his wife, Gladys Amor (nee Tierney), and embarked from Sydney with the 21st reinforcements to the 13th Battalion aboard HMAT Ceramic. Amor served with this unit in France and was also a member of the 13th Battalion Band. He returned to Australia in 1919 and went to work on the tramways in Sydney. William Amor died at Chatswood, aged 51, in 1942.
