If I have the correct man, he is with his mother in law Ellen Gidman in 1911. His occupation says Worker 4th The Kings Special Reserve.
Correct Man Comberton! I need glasses as I found 1911 Census and missed that on his Occupation line.
Found He Married Margaret Gidman 9 October 1910 Occupation Rubber Tyre Maker
The 1911 Census attempts to name their 2 Weeks Old Daughter- Eileen Josephine and Adam's Occupation - Rubber Warehouse Worker - but added King's 4th Reserve.
The Family Portrait I found of Adam in King's Uniform with Wife Margaret and Daughter Eileen must have been taken mid Summer 1911 as Eileen Died December Quarter 1911 aged 0
It proves AllanUK theory that he was in the King's before the War and Enlistment Date given on Silver War Badge Card of 15 May 1915
