Liverpool Echo 11th June 1915

   News came to hand in the course of the week announcing the death of Company Sergt. Major Jefferson, of the 7th King's, who was killed in action on the 16th May. He was the son of the late Mr. Thomas Jefferson, and resided at 181, Bedford-road, Bootle, and prior to the outbreak of the war was a clerk in the service of the Great Western Railway Company. He was at all times an enthusiastic soldier, being connected with the old volunteers. He continued to take a keen interest in the Territorial movement, and ultimately was promoted to the rank of Company Sergeant-Major. He was one of the most popular N.C.O.'s in the Battalion, and those of his pals who were fortunate enough to come out of the terrible charge alive, deeply mourn his loss. In Bootle he was well known and highly esteemed, being connected with a number of local Lodges. He constitutes another link in the chain of Bootle heroes.

JEFFERSON, - In loving remembrance of my brothers, Jim, C.S.M. James Jefferson, 1/7th Batt. K.L.R., who fell in action at Festubert, May 16th, 1915.
   Jack, who died January 16th, 1919.
   Harry, who died February 18th, 1919.
Only a glimpse of by-gone days.
And a sigh for faces unseen;
But the constant feeling that God alone
Knows best what might have been.
