In a letter dated 23 February 1983 to Muriel Leo (nee Oliver) from Margaret Oliver (nee Eves) where she wrote that this Fay Christiansen [nee Andrews], “and her husband [Keith] were hurt in a car accident last month. Fay was quite badly hurt but her husband did not seem to have been hurt so much and after a short time in hospital was with his daughter where he died suddenly on Jan 21st. Fay died on the day before his funeral was to have been, so it was a double funeral”.
