Private Walter Simpson Brown was born at Little Casterton, the son of Charles and Mary Brown. He was 32 years old and worked as a wheelwright. George Phillips wrote that although suffering from bad health, his motto was "Deeds not Words" and being determined to do his bit, he joined the 1st/4th Battalion York and Lancaster Regiment on 25 August 1916. He went to the front, but his health broke and he was sent back to England and died in the Birmingham Military Hospital on 31 July 1917. Walter is buried in Stamford Cemetery, grave L.22, with a private family headstone although the Commonwealth War Graves Commission maintains his grave. He is also remembered on Little Casterton's war memorial and on Stamford's war memorial. A plaque which was once in Toll Bar Methodist Chapel also has his name on it. It is now in Little Casterton church.

To find Walter's grave: enter Stamford Cemetery and turn right towards the chapel. Take the path on the left side of the chapel and walk up about 50 metres. The headstone is on the left in front of a yew tree.
