This is what I know.
From the "Weald of Kent...."database, IGI and family tree names
Edward Robert John Heasman (B 10.1.1904 E Grinstead Sussex) married Marion Isobel Ash (b10.1.1907 Kettering Northampshire) on 27 May 1931 Sussex.
I presume it was Angmering as this was where their daughter(Christine Mary Heasman) was born and died in 1936.
What I do not know, is what happened then, as Marion died i19.6.1985 (IGI) in Creston British Columbia and Edward 15.9.1957 (IGI) in Auckland New Zealand.
There are 2 possible outcomes - they separated in England, or they both went to New Zealand and Marion then went on to British Columbia after Edwards death.
