Hi Brian,
I am doing some research on the War Memorial in Earsham, Norfolk. There is one LW Saunders listed in the WW1 section, and listed on a plaque in the village hall as Leonard W Saunders in the 9th East Surreys.
The trouble is, that is where the trail runs cold. No other websites, including the CWGC list such a soldier. The closest I have come up with is a Private William Saunders, 2293, 9th East Surreys, 3rd Sep 1916, Serre Road Cemetery No2. XXXIX. C. 15. I cannot find anything else about this Private William which would link him to Earsham or Norfolk/Suffolk.
Do you know anything about either of these?
