One Geni-User believes (apparently based on a very idiosyncratic idea of interpreting DNA matches combined with believing some people do not look alike, etc.) that his biological lineage does not match the one shown by documentation.
We now have
1) The person he believes is his biological paternal grandfather: David Walter (MSB) Bloom which I see currently as <private> Bloom but used to see as David Walter Bloom
2) And the person he believes is his biological paternal grandmother: Private whom I see currently as <private> Siegel
3) And the person the records show is his paternal grandfather: Yaakov Bentzion/Jankel Bentsel, later Jacob Siegel which is currently Public and I see currently as Jacob Siegel
4) And the person the Records show is his paternal grandmother: Mary "Merka" (MSB) Siegel whom I see currently as <private> (Bloom) Siegel but used to see as Mary (Bloom) Siegel
According to the Geni-User, his father's mother is the Rose, whom the documents show as his father's sister. And it definitely does sometimes happen that a child may be adopted by their grandparents and brought up as their child rather than grandchild.
So Mary is either the Geni-User's grandmother or great grandmother.
But ...
----
The father of Mary is Herbert (MSB) Bloom
Herbert had been showing 2 wives, with Mary the child of the first wife. Multiple sources reported Herbert had three wives, with children by each.
We discovered a marriage record for one of his children, confirmed as the correct marriage record by a grandchild of that child of Herbert's.
I added a profile for that wife, now giving us all three wives, and changed the parents of her child accordingly.
Given the records we had, we now knew the order of the wives. Given the order of the wives and the birthdates of the children, it was clear Mary was not the child of the first wife. I changed the parents of Mary. I annotated all this on the Overview of Herbert = Herbert (MSB) Bloom. This was on the evening of Oct. 26.
Personally, I expected that change to Mary's parents to last at most two minutes.
The Geni-User never changed the parents back.
There was / is a Public Discussion about Herbert's first wife -- https://www.geni.com/discussions/239814
We had reached the point where it was clear to us that Herbert's first wife, Frieda was not the same Frieda who married Emil Kamm.
The same Geni-User is adamantly insistent that they are the same Frieda.
On the morning of Oct. 28th the Geni-User apparently discovered something about the change we had made to Mary's parents.
He refused to even answer the question if he had ever obtained Mary's Death Record (which I asked here: https://www.geni.com/discussions/239814?msg=1517232)
Another user. asked him "what are the DNA matches that suggest that you are descended from Raphael Kamm? Who, how much shared cM, etc.?"
(https://www.geni.com/discussions/239814?msg=1517249)
To which he responded "I already submitted it to Mike Stangel with everything. Please fix it up on my tree."
To which, yes, I stated "If you want me to "fix it" the way you want it, then you have to convince me that you are correct."
Thinking that might inspire him to respond to one or both of those two previous questions.
I could not have stopped him from changing her parents back himself.
I do not know why he did not do so.
On 11/2/2021. Customer Service, instead of
1) insisting that Geni go with the evidence or
2) changing Mary's parents back, mastering her, and putting a note that there was a dispute over which of Herbert's wives was really her mother, but a direct descendant was adamant it was Frieda, and they were accomodating him,
Customer Service went with
3) apparently created a duplicate of Herbert and Mastering the original Herbert = Herbert (MSB) Bloom with a Curator's Note up top: "Curator Note from Customer Service (11/2/2021):
Please do not merge with duplicate brother Herbert Rosenberg Bloom -- we have split / duplicated the bottom of this tree in order to accommodate users who cannot agree about parentage further down."
So now we have lots of duplicates and, it seems to me, a major mess.
