Well, It just goes to further support the statement that there are a lot of very dodgy family trees out there online.
Unfortunately researchers blithely copy large slabs of information from online trees and accomodate them into their own family history. There are no rules that say you can't do this.
No doubt the death of AMBROSE EYLES in COLLINGWOOD MELB. is already a firm fact in someone's history because you have published it as so.
However, we live in the modern communications age

and such things will continue to be an issue.
