Born John Francis, son of John and Margaret Forde nee Rourke. His father, born in Co. Galway, was a constable in the RIC and later an insurance agent. His mother was born in Co. Wexford. Later resided at Patrick Square, Wexford.
A clerical worker in the Pierce Ironworks Foundry in Wexford, Frank joined up aged 16. In early August 1916, he arrived in France and fought at the Battle of the Somme. However, just a few weeks before his 17th birthday, Frank was grievously wounded during the Battle of the Somme and died while being brought back from the trenches for medical attention. His platoon commander, Lieutenant A.W. Henchy wrote to Frank's parents and called him 'a fine courageous fellow and a gallant soldier of whom his family should be proud'. Frank was buried in Trachee de Mecknes Cemetary in the Pas de Calais in France. In his military will, he left everything he possessed to his mother.
