Jacob Yehuda Rosenberg - DNA Wanted

Private , great-grandson of Max Rosenberg Bloom , has tested through Ancestry. I don't know if he's also tested elsewhere nor if he has Y-DNA results available.

I just see him as <private> Bloom but do see that he is
son of Melvin Bloom -- son of Samuel Bloom -- son of Max (Mordechai) (Blum or Rosenberg) Bloom -- son of Jacob Rosenberg
So yes,apparently a direct male descendant of Jacob thru Jscob's son Max

He is not a Geni user. Private User are you by any chance in contact with him?

Unfortunately, no, I'm not.

(I did just send him a message through Ancestry, though. Here's hoping he responds!)

In https://www.geni.com/discussions/239445?msg=1515999
that was posted on 10/25/2021, Private User ,
a great grandchild of Herbert (Herzl) Bloom states that Ancestry shows him
"Stephen Bloom 3rd cousin 10cM /2 segments"

I have now spoken to Steven Albert and he reports he does not match Stephen Bloom, nor does his brother, nor does their first cousin Diane - all of whom are great grandchildren of Herbert Bloom.

About 10% of the time, 3rd cousins do not match -- so one of them not matching would not prove anything.
But 3 of them not matching and the one that we know of that does match only sharing 10 cM - is that enough to conclude that Herbert (MSB) Bloom and Max Rosenberg Bloom do not share the same set of bio-parents?

Besty Hernandez (Lacher) is related to Stephen bloom by half 3rd cousin once removed.

MITCHELL SIEGEL and Steven Albert could be half 2nd cousin through:
Freida kamm
Great-grandmother

Private User -
Is that relationship between Betsy and Stephen Bloom based on DNA or on a Tree someone created?

How many cMs of DNA Ancestry says people share over how many segments is concrete information.

A relationship based on DNA shared is just an estimate, and very often wrong.
A relationship based on a Tree is only as good as the Tree.

Are you and Betsy the only two who share DNA with Stephen Bloom?
Not Jess or Alex or etc.?

Thrulines suggestions of relationships are NOT based on DNA.
They use the fact you share some DNA to choose to look at Trees, and base their comments about relationships on the Trees.

My great grandmother is Bessie Kaplan - Herb Bloom's second wife. Mitchell and I have to be related via Herb and the DNA match with me, my brother and 1st cousin all support that being a 1/2 second cousin. Based on info I have, Dave was a child of Herb's first wife, Sarah was a child of Herb's second wife and Mary and Lilly were children of Herb's third wife.

Steven Albert I found Helen Winer is related to Steven Albert by 4th Cousin via MyHertiage. Sarah Cohen (Bloom) is related to Freida Kamm

Louis's cM is higher than Steven's cM from me.

Louis
1st cousin 1x removed | Parent 1's side
5% shared DNA: 340 cM across 18 segments

Steven
Half 2nd cousin or 2nd cousin 1x removed | Unassigned
3% shared DNA: 178 cM across 12 segments

Private User - Siblings often differ.
If you look at the chart for the Shared cM Project at DNA Painter, https://dnapainter.com/tools/sharedcmv4
you will see that
for 178 cM, the second group, for 36%, includes 2C
for 340 cM, the second group, for 46%, includes 2C

If you look at Lara Diamond's website, for Ashkenazic Shared DNA
you will see that for "All responses (regardless of Ashkenazic percentage)"
for Second cousins the smallest shared cM was 6.8, the largest was 698, average was 273.34
So one of them was higher than the average, one was lower than the average, they are both within the range.

This Public Discussion has nothing to do with Frieda Kamm. That comment is irrelevant here, and I would appreciate it if you would move it to a different discussion.

Private User -

Can you get Betsy's permission to share how much DNA she shares with Stephen Bloom? That would be helpful.

Also - are you and Betsy the only two you know of who share DNA with Stephen Bloom?
(or Just you?? Or ??)

The website I was looking at for Lara's info - https://larasgenealogy.blogspot.com/2019/09/ashkenazic-shared-dna-s...

Betsy shares 21cM with Stephen Bloom. other cousins D.Nathan 24 cM and J.Nathan 24cM

Private User - Thanks much.
Are D.Nathan and J.Nathan descendants of Herbert (Herzl) Bloom, or ?

Other different Stephen Bloom shares 20 cM with me and he shares 31cM with Betsy

Me shares 99 cM with Julia Nathan by 3rd cousin. Diane E. shares 29cM with Julia and Betsy shares 20cM with Julia

Julia's daughter D. Nathan shares 146cM with me

D. Nathan shares 26cM with E. Aarons (my grandfather David's daughter Elaine Bloom)

Sounds like Julia Nathan and her daughter D. Nathan were not already known descendants of Herbert (Herzl) Bloom, nor of Jacob Yehuda Rosenberg.

So only 2 of the almost a dozen known descendants of Herbert (Herzl) Bloom with DNA results at Ancestry are matches to Stephen Bloom, who is a great grandchild of Max Bloom.
So the DNA definitely fails to prove Max Rosenberg Bloom and Herbert (MSB) Bloom the same bio-parents. Rather, it strongly indicates that they do not.
In other words - the DNA very strongly indicates that
at least one of Max Bloom and Herbert Bloom are not children of Jacob and Toba (Fine) Rosenberg

You mentioned this DNA results are wanted from descendants of each of Jacob Rosenberg's children, or as many as possible.

Have any descendants of Max (Mordechai) Bloom tested??
Have any descendants of any of his sons who used the surname "Rosenberg" tested?
Is there Y-DNA from any direct male descendants?

FamilyTreeDNA (familytreedna.com) is having their Black Friday Sale - Thru Nov. 30, the Family Finder Test is On Sale there for $39.
This is $20 less than the usual Sale Price, $40 less than the non-sale price.

I did send it to the four managers for Private on 9/22/24. They never replied it to me.

Why did you put her private profile Private

This is my third cousin profile on Geni public.

That sale ended last November. There will probably be another this November - with the best often being over Black Friday - over or right after Thanksgiving.

But its good to hear you tried.

Most of the profiles that might still be living and many of those deceased are private to me so I cannot see the first name nor work on them.
However, I have extended at least one of the lines a little recently.

There is so much endogamy amongst those of us with AJ Ancestry, I also tried a search on Ancestry for anyone with "Jacob Rosenberg" in their Tree, but it spun for a long time, then returned to my full match list - which I suspect means it timed out.

Private User -
I have added several descendants of Jacob and Toba Rosenberg. recently, others at various other times
That profile is Macy Broide - he is one I added from a Death Notice of a parent - so far I have no date of birth for him, and do not know if he is still alive.

I was thinking - in your Max family so you could see.
Is the fact there is blocking keeping you from seeing it? It did not used to be that way, but I am thinking now I read maybe they changed things.

Private User -
For profiles which are descendants of Jacob Yehuda Rosenberg --
I know you are interested in that lineage, so I was trying to be kind and make more Public -

BUT -
I see when I do so you add yourself as. Manager --
And you are only able to add yourself as a manager because you attached your ancestor Herbert (Herzl) Bloom as a child of Jacob Yehuda Rosenberg
I100% do not believe Jacob Yehuda Rosenberg is the father of Herbert (Herzl) Bloom and I think it is pretty well proven that he is not
But again, being kind I had not yet detached him.

Please remove yourself as Manager of those you added yourself to in the last 24 hours and promise not to do any more, or I will stop making the ones I manage Public.

Also, if there is no good reason people should believe Herbert (Herzl) Bloom is a child of Jacob Yehuda Rosenberg then that connection should be removed, especially since the DNA has now pretty clearly shown Herbert is not a brother of Max Bloom.
The discussion about cutting that connection is here: https://www.geni.com/discussions/280063

Based on comments in https://www.geni.com/discussions/284222
It seems Private
is Marvin Bloom son of David Hyman Bloom son of Max Bloom
And
Mitchell Siegel-Bloom is son of Herbert Siegel son of David W Bloom son of Herbert Bloom

So if Max Bloom and Herbert Bloom are siblings, and if those are correct
Then Mitchell and Marvin are second cousins once removed.

It also says Marvin and Mitchell share 56 cM at FTDNA.
And their suggested relationship is 4th Cousin to remote
And Marvin shows as having Y-Haplogroup R-PF7563
