AADR v66.0 (Allen Ancient DNA Resource)

Yeah commercial stuff is good for some people but crap for others. It’s extremely good for Ashkenazi and Sephardic Jews, like so good that if you score some it’s reasonable to take it literally instead of saying “could be Mediterranean or EEF” (but in some cases it could just be noise if it’s tiny enough) Lots of Hispanics score percentages of Sephardic.
I haven’t tested partially bc my results would be very predictable, but might be fun. All ancestors were in Europe till like late 19th early 20th centuries.
Anyway sorry to diverge. G25 along with the other hobby calculators would give weird results so yeah I’d avoid them. Stick to the ones used in scientific research
 
Z value of 2 is permissible, but 3 is ideal. Nevertheless, I think this is plausible historically considering the Normans.

Good thing you’re using samples from the same timeframe! I sometimes see wacky modeling where they combine EEF with I dunno, ancient Persians (I’m pulling these examples out of my butt) which is silly.
Do you get a better or worse fit when you take the Viking out and leave the medieval Italian in?

It is not necessarily silly, because even when you are modeling ultimate source ancestry, you are compelled to use Mesolithic HGs, with Neolithic Farmers, and Early Bronze Age Pastoralists. If anything, it helps map out a broad trend, rather than a definitive source. For example, I can model myself as most Middle Bronze Age Apulia, but with 25% residual Steppe. Demonstrating a proclivity towards Steppe, from the Mostly Anatolian/Iran_N MBA Apulian source.
 
I can see that to account for deviances or variations from the norm. They exist in every group, your steppe is noticeably higher than the average Apulian. So it would make sense to model you as such plus extra steppe.

I'm pretty standard actually, Apulians range from Central Italians to Deep South.
 
Wow, they go that far north? Very interesting. It is a fairly elongated province so I can see that.
 
That’s fascinating! Even northern Latium isn’t far off from southern Italy genetically. It’s not far from Sicily even. Im pretty sure southern central Italians are genetically fully south Italian and would land in one of those clusters if even northern Latium can get that close.

Central Italians with the exception of Tuscans, are basically genetically southern Italians for the most part. Of course there's a cline, but Italians are made up of two main clusters; north and south. With the repopulation of Rome, we see the C6 cluster became dominant after the depopulation of Imperial era migrants. The repopulation was mainly driven by C6 (central Mediterranean) which is likely a confluence of Italic and Balkan/Aegean populations.

That confluence could predate Rome, as we see BA Apulians (not Daunians) align similarly on the PCA.

So it’s been like that for ages. It’s not just a recent thing, like south Italians moving north but an actual cline that’s been around for centuries. I knew imperial Rome had more south Italian like people even further north and this pattern must’ve survived even after the party was over with Rome. I’m willing to bet the southern parts of Latium are campanian like genetically speaking, since it’s close enough to the border and if the average northern Lazio Italian can get that close to those southern clusters, then I can’t see how a southern Lazio Italian can’t be campanian like since they’d be genetically more southern and geographically closer to campania.
Anyway this is really cool, thanks for sharing this!
 
Is it me or does north Latium score some freakish Anatolian farmer even for Italians, it seems to get dragged down closer to those Sardinians. Maybe it’s just a pca “thing”, we know they don’t always paint the full picture.
Maybe try modeling that sample (when u got time ofc)? It would be cool to see and it wouldn’t stray far from the topic tbh!
