Rose Ball Henninges is buried at Burwood Cemetery (near Melbourne, Victoria, Australia).
The Grave reference is: METH Section 8 Grave 102, which is the same grave as her husband's.
As those who have a picture of her husband's headstone, Rose's name does not appear on it. Hence her name is not listed on the transcription of headstones available at libraries and historical societies.
If you want to visit the grave, it on the left hand side looking south from Burwood Highway, just beyond the first roundabout.
I have temporarily provided a picture of the grave at:
Now for my next question: who can provide photos of Ernest and Rose Henninges?
