What I know from family members
My grandfather 's brother was killed in Belgium later half of 1917 and was a Machine gunner no first name just the surname of Smith (not a great starting point

What I have found
My grand father (Thomas) had three living siblings on the 1911 census, James, Sarah and Edward both Sarah and Edward attended my parents wedding in 1963 so by elimination that leaves James as the brother killed in WW1.
Searching Ancestry etc. I find
James Smith Born Wolverhampton, Staffs
Death 26 Oct 1917 Location France & Flanders, K I A
Enlistment Wolverhampton
Rank Corporal
Regiment Machine Gun Corps
Number 7416
Formerly 18789, S. Staffs Regt.
CWGC only Gives his Rank Initial and Surname and no more.
As far as I can see this is the only James Smith that meets what I knew from family members, is there any where else I can search for more information to link this James Smith to my family?
or how confident can I be that this is the one i am looking for?
Sorry for the protracted post
