Thank you for last couple of bits of info. Now found Evie in 1939, waiting for my cousin to open it. Still not got her death?
However have found the daughter of Evie & Arthur jun, her marriage & child.
Now have an address for dau & husband and even a telephone no. How's that for result?

?
This had been a "brickwall" for many a year.
Thank you everyone for all your help, much appreciated.
