Dennis was born in 1891 and his parents were Alfred and Jane. He had two older sisters, Bertha and Alice, and two brothers, Alfred who was older and William who was younger.
In 1901 they were living in 7 Desborough Avenue but by 1911 had moved to 49 Baker Street. In 1908 Dennis won a County Council prize at the School and at the time of enlisting was working as an upholsterer at Messrs William Bartlett and Son. In early 1913 he married a Miss Woodbridge and they lived together in St. Mary Street. By 1916 they had two children, one was called Bessie who was born in 1913.
He joined the 14th Battalion of the Royal Warwickshire Regiment in April 1916 and had only been in France for about 8 weeks when he was killed on September 11th 1916. He is buried in Corbie Communal Cemetery Extension in the Somme. This cemetery was used by two casualty clearing centres and it is likely that he was brought here having been injured fighting in the Battle of the Somme (probably the Battle of Guillemont, which his battalion was fighting in up until September 6th.) His listing with the Commonwealth War Graves Commission can be found here.
