As I suspected I did miss these names (I blame old age) but the additional info helped.
1918 Autumn Absent Voters List Berwick (ER1-32)
Chatton Polling District
Parish of Chillingham
Renner, David Richardson
Chillingham Barns
M/334701 Pte., 52 Co. M.T. A.S.C.
Renner, Thomas William
Chillingham Barns
49109 Pte., 16 R.S.
Then there is another list which is entitled
1918 Autumn Record of Addresses Berwick (ER1-33)
This appears to be the same as the above but there are handwritten notes at the end of each line, presumably to say where the men currently are. These have entries such as B.E.F., no trace, etc
For David Richardson RENNER the note says Aldershot
For Thomas William RENNER, the note says P. (though that may have been a scribbled B) E.F.

No mention of Thomas William Renner on this 1919 list.
Neither of these men are listed on either the Spring or Autumn lists for 1920.
I have visitors arriving shortly, but will double check for the Benton names later.
