@Rigger - was the Bedlington Community Centre - Creatives Group, that have done a lot of research on Bedlington soldiers to create their 'Poppy Map' one of the usual sources you have tried? They produced a list of Bedlington Soldiers' 'Poppy Map'  and I believe they have retained info that they uncovered in their research :- http://www.bedlingtoncommunitycentre.co.uk/ Address: 60 W End Front St, Bedlington NE22 5UB Phone: 01670 824141
