Re: Eliza Hawkey Nee Snell
I have knowledge of this lady as part of my research into the Snell family (Origins: Cornwall, from where Eliza's parents emigrated to Australia in 1854).
I don't have details of her burial, but I note that the Victoria BMD site has note of a death of Eliza Hawkey in 1920 and, assuming that's her, it's possible that the associated death certificate would show burial location. Have you tried that?
