Ivy and Len Gregory

Wedding photo of Ivy Howard and Len Gregory. This is my mother's Uncle Len, my grandfather's brother.
His granddaughter, told me that he was a fireman in civilian life and then stayed in London during the blitz in WW2 as a firefighter. In WW1 he was in the Royal Dublin Fusiliers and his dog tags give the number 40877RDF
