Thomas was born likely on the 30 December 1884 in Cloonaugh, Drumlish, Co. Longford, but later moved to the north of England with his family. Pte O'Neill enlisted in Warrington, Lancashire and engaged in the war the 5 August 1915; he initially served at Gallipoli before being deployed to Belgium. Prior to the 27th his battalion was stationed at an area in Belgium known as Red Lodge, where they assisted the Royal Engineers in stengthening the trenches. On the 29th, four companies of the 2ns Leinsters relieved the 7th Northhamptonshire Regiment; here Pte O'Neill and Pte Malone (No.350) were killed by a shell 30 minutes after relieving the Northants; 24 men from the 2nd Leinsters rank-and-file, and two officers, were killed during March 1916. After his death, Thomas's uncle Patrick is noted as being his sole legate.
Pte O'Neill was initially buried in the Ploegsteert area, in the Rosenberg Chateau Military Cemetery.
