He was the husband of Anastasia Adcock. Little is known of William’s background, given that he was 22 years of age when he fell in action, his year of birth would have been circa 1896, and although the entry for William in Soldiers Died in the Great War shows his place of birth as Leicester, there is no William Adcock recorded as being born in that year in the registrations of births for Leicester.
In the 4th quarter of 1915, William married Anastasia (Annie) Parle (Perle) in Leicester, and her home address was recorded in the 1918 War Pensions Register as being at 153, Noble Street, Leicester, Anastasia was born on the 24th September 1890 in Derby, and during the 1920’s continued to reside at 153, Noble Street, with her older married sister Elizabeth and John Irwin. Anastasia died in the 2nd quarter of 1925 in Leicester, aged just 34.
William’s Army enlistment documents do not survive, all that is known of his military service is that he enlisted into the King’s Royal Rifle Corps, being allotted the service number 37947. He was at some point transferred to the 1st Battalion Machine Gun Corps and allotted the service number 103776, and it was while serving with this unit that he was killed in action on the 20th April 1918. He was awarded the British War and Victory medals.
