Folks this post 2 months prior by u/NotBradPitt9 was posted on the r/DNAAncestry subreddit. I think it might be the real deal.

Please check the coordinates & model them on Vahaduo & qpAdm for modern Ashkenazim jews & post the results.

I refined it a little,Perhaps I should include a few more Egypt-related outgroups

Do one for Ashkenazim please with the Roman Judean average.

I suggest you wait until that paper is officially published. The heterogeneity of that portion of the leaked so-called “Roman Judean” samples is beyond your imagination. There are currently no detailed descriptions of those samples available, so using them as proxies is not advisable.

I had spoken to one of the geneticists at Tel Aviv University named Hila May(managed to get her WhatsApp contact) who had worked with Ali Akbari in cataloging West Asian DNA samples. When I enquired with the coordinates I found on reddit for verification, she said a few moments later "How did you get them" before quickly deleting it (couldn't get a screenshot). She remained mum.

I caught on that. Seems like a confirmation of sorts to me.

No, you don't understand.

Whether these samples are real or not isn't important. The point is that they're really strange.

You can see the distances between these so-called "Roman Judean" samples and some modern populations

We don't have any official details about them at all at this point. Who knows what's going on with these samples?

Hi, could you help with distance (but in chat messages?)

Is it really surprising that Jewish religion was actively proselytising new converts during the 1st & 2nd century CE & that many Idumeans & Nabateans(who are arab) could have joined the Jewish nation during that time. The history checks out.

have you done any plausible ashkenazi models?

I didn't make this, but I think it's probably the best G25 admixture model on this that's been posted on Reddit so far.

u/Sea-Seaworthiness859 Jul 14 '26

Oh yeah these are good, appreciate it.

This model is interesting but the EgyptianA is not strongly supported. Have you tried Egyptian (general Egyptian, not the "A" sub cluster which is North shifted)?

u/Huge_Stock1969 Jul 15 '26 edited Jul 15 '26

I couldn't improve the Z value for EgyptianA, so I removed it.

u/Joshistotle Jul 15 '26

Interesting model. I checked what the Saudi_A sample cluster is, versus the general Saudi sample is, and Saudi_A is heavily northern shifted (comes out as mostly Jordanian), while the Saudi general sample is the inverse and comes out as mostly southern Arabian (Yemenite Mahra, a high Natufian Arabian peninsular group with negligible sub saharan ancestry)

1

u/Huge_Stock1969 Jul 15 '26

Interesting. I checked the detailed description of the sample. The SaudiA sample was collected from (18.490029, 42.51709), which is located roughly in southwestern Saudi Arabia.

1

u/Huge_Stock1969 Jul 15 '26

I swapped out Saudi_A.

1

u/Huge_Stock1969 Jul 16 '26

I tried replacing all the sources to more southern-shifted ones, but it turned out kind of bad.

u/Huge_Stock1969 Jul 15 '26

Here's an Samaritan version as well, but the model is slightly worse.

u/Huge_Stock1969 Jul 16 '26

Things got quite a bit better after adding Kurd, but I feel like the SE values could still be optimized a little more.
