Well Lois, as Eldon and many others here say: This discussion is never going to come to a resolution. And why not?
I bought the World Tree idea and could give my family-tree and when that is done, since we are several descendants and other Geni-users helping, we are all able to do other things. Why so? Well we can all add information about others we are not genetically connected to and help each other outside the close family and by that work towards the World Tree. I know the idea is just a goal. A parade goal, but although a goal for the sight Geni.
So why chose Geni for keeping a private connection within the close family extended to 1790? That will sort out the big emigration from Sweden to USA in the 1800:s. If interested in kings and notabilities even the murder of king Gustaf III would fall out from Geni. The complete project of "Mormone pioneers" will fall out from Geni. The New Sweden project will be left. But none of the Victims of the Holocaust will be public. In my point of view that's the most moral sane thing i can think of, since every single person murdered in the holocaust will not be named on Geni. Everyone in Europe and USA knows for sure they (who?) were killed.
And Lois way of thinking leads us to make that a private matter, as all the victims was killed so late in historical time!!!
