Well, All speculation at present, but this could be a NSW marriage.
The wife in the divorce item is named as MARETTA
REG 3012/ In 1916 KING ERNEST E
To HORRIGAN LILY M
WOLLONGONG
And is this the death of a child of the couple
15456/1975 KING REGINALD JOHN
Father ERNEST
Mother LILLIAN MARETTA
Is this a child of ERNEST EUGENE. Possibilities only.

Have you more information at all?
