Hello all, I'm a new member, born and raised in Cramlington. I'm trying to find out anything I can about the grocers' stores my great-great-grandfather used to own in East Hartford. His name was William Milburn - I don't know when the shop was opened but I think it closed down in the 1930s. I've tried google and poring over old maps, but no luck so far. Has anyone come across it in their research? Many thanks in advance Emma.
