30 July 1917 I wonder what has become of Ted Gerrard

 I believe the Ted Gerrard he is mentioning is Edward Gerrard who also attested in the 142nd Btn in London Ontario. His regimental number was 823133. He is not listed in the Commonwealth War Graves Commission data base, so I presume he survived the war.
