1939 he and Mary are in Birmingham. DOB 1 July 1893. I'm struggling before and after the marriage. I note the eldest child is registered as Mary but is on 1939 as Iris M, so I wonder if he's swapping order of forenames.
Given he married during WWI, he could have come from elsewhere and met Mary Ann whilst stationed in the Midlands. I can see 7 Normans registered Q3 1893, none of whom are particularly local
