Jacob was born in Wolverhampton in 1885, the son of William and Susannah Walton. In 1901 they were living at 7 Willenhall Road, Bilston, along with Jacob’s siblings Joseph, Henry, Mary and Minnie. From 1903 onwards, Jacob enlisted in the Militia, and served in the East for six and a half years. In 1911, Jacob was serving in India. He returned home on Reserve, and married Martha Ward in Wolverhampton in 1913. The couple had two sons, James (1917) and John (1918).
When war broke out, Jacob was recalled, and served with the 2nd Battalion of the Royal Welsh Fusiliers (number 8427), first entering the war on 22 August 1914. He was involved in many engagements, including Mons, and rose to become Corporal. On 15 April 1918 he was wounded, and he subsequently died of these wounds on 30 April 1918 in the 3rd Casualty Clearing Station in France. Notice of his death appeared in the Midland Counties Express on 18 Mary 1918. He is buried at Bagneux British cemetery, Gezaincourt, and he is remembered on the Bilston Town Hall Ward Roll of Honour.
