I looked up the death notice. Nothing new there.
SMH, 28 Mar 1981
FALLS, Maurice Terrence - March 27, 1981 (suddenly) - beloved husband of Norma, loved father of Maurice, Dennis, Robert and Richard, fond father-in-law and grandfather of their families.
Aged 58 years. At Peace.
I also notice a coupl of Falls in NSW and Queensland with Terrence in their names. Might be worth pursuing.
