G'day Jeff, Your deduction was spot on. I popped into the Library at Darwin today to check out the Death Index of which I do not yet have. On the Diggers Death Index (1921 - 1985) listed are three deaths for SPILLARD.
Euphemia SPILLARD d:1929 at RMOND (Richmond)age 80. Reg No.7080 father: Jno TELFER. m: Ann SMITH There is no mention of a death for her husband,Peter SPILLARD.
