Thank you for your help. Arthur G Barr married Daisy Cooper in Alverstoke in June 1916 quarter 2b, 1266, according to my research.
It appears that Daisy went back to her family town in Halstead, Essex to have their daughter Pamela Barr, births December 1917, 4a, 1109.
By December 1928 quarter Daisy had married a Mr Henry W Curtis and Arthur had disappeared either deceased or divorced.
Someone by the same name did Arthur G Barr did marry another person too around the same time !
