We are trying to research a great aunt born Emily Barfield in Great Oakley in Essex England in 1888. We know that she married a South African man known as either Lal or Lol and had a son David (pet name Davo) born 1932. We have a letter from 1937 coming from 101 Oak Avenue, Primrose, Germiston. We cannot find a marriage in England, the last we can find is her, still single, on the 1911 census. We think she died around 1964 in South Africa. We also know that David was in the South African Air Force. Any help gratefully received.
