Hi everybody,

I would like to dedicate this specific thread to my own small but nevertheless interesting subclade FGC3273. I would also like to stimulate a discussion about its possible origins and its current distribution and discuss actual new results. The reason I decided to open a new thread is a brandnew result: FTDNA kit 438809, the only Yemeni Jewish kit in the J1 y-DNA project (with Levitical status!) has just turned out J-FGC3708 and we'll see soon if he's also FGC3706 which happens to be my subclade. Actually he's Z18258- and also Z18256- which is the other relevant subclade under FGC3708. Right now we have a FGC3723 concentration in Yemen and Saudi Arabia (Hijaz). The distribution map shows you that it could be present sporadically all over the Middle East. We have a Greek sample, a Portuguese one, a whole cluster in the Southern German speaking area (Germany and Austria). Quite a lot of Arabs with a Hashemite (Quraish) oral tradition, a Kurdish Jewish Kit and three Yemeni Jewish samples one with Levitical roots. One clade under Z18256 belongs to the Yafi tribe in Yemen but also other tribes like Madhhij, Ans, Akk, Nimr, Thaqif and Shammar and some others are present within FGC3723 and many samples claim a Himyarite origin! The clade is also present in Eritrea and Ethiopia maybe due to Sabaean colonies in the 2nd millennium BCE.

The current distribution map can be found here:

Hello
Interesting to see that you have J1-FGC3706 as your paternal haplogroup. We have J-FGC3708 as common SNP. Do you have any family history that links you to the middle east (assuming of course this subclade originated in the this region) ?
btw I also have Himyarite ancestry.

An association with Old South Arabian is extremely likely, IMO FGC3723 will be found in Razihi speakers.

Had never heard of Razihi, and had no clue anyone thought there were extant descendants of Old South Arabian. Thanks for the info! Surprising little material to browse online.

Hi nice to meet you! I have no ties to the Middle East, my family is Austrian and I have no idea how we ended up being here. FGC3723 was first discovered a few years ago in the FullGenomes y-DNA sequence of my sample and I am still continuing to research it. It's a rather interesting and surprising subclade of FGC11.

No, as fas as I know it's not present in Ashenazim, but in Mizrahim (Oriental Jews) as we have three Yemeni Jewish Kits and one Kurdish Jewish kit. The Kurdish Jewish kit's linguistic background is Aramaic.

There are quite a few origin scenarios possible: my ancestor could have been a Yemeni soldier ending up in the Roman army or a Frankincense trader. Just remember that Minaean (Old South Arabian) inscriptions have been on the Greek island of Delos! In addition he could have been - at least in theory - also Yemeni Jewish. But this is all mere speculation and none of the scenarios could be true as well as we still don't know the distribution pattern of FGC3723 4000 and 3000 years ago. But the Yemeni Old South Arabian association is quite strong I'd say.

FGC3723's TMRCA is about 5,000 years old.

My personal guess is that it is quite a few centuries younger as FGC11 as a whole is estimated to be only 4600 years old, FGC3708 ca. 4300 years and FGC3706 (my subclade) ca. 3200 years while Z18256 is about 3800 years old. My closest SNP-match (FGC3706+) at the moment is a Yemeni kit belonging to the Al-Rassi family claiming descent from Ali. We'll see in a month if the Yemeni Jewish kit will eventually turn out to be also FGC3706+. All these dates are from Victar's J1 tree.

Sorry for the three consecutive posts. Would have prefered the multiquote function.

Thanks for mentioning Razihi, which meanwhile is believed to be a direct descendant of OSA altough it is still not very researched. Angela Watson published 2011 a paper investigating the ties between modern Yemeni dialects and OSA referencing and quoting examples from Razihi:

South Arabian and Yemeni dialects

ABSTRACT
It has traditionally been assumed that with the Islamic conquests Arabic overwhelmed the original ancient languages of the Peninsula, leaving the language situation in the south-western Arabian Peninsula as one in which dialects of Arabic are tinged, to a greater or lesser degree, with substrate features of the ancient South Arabian languages. The ancient Arab grammarians had clear ideas concerning the difference between the non-Arabic languages of the Peninsula and Arabic, including the -t feminine nominal ending in all states and -n versus the -l definite article.. Today, however, we read about ‘Arabic’ dialects that exhibit large proportions of ‘non-Arabic’ features. Here I compare phonological, morphological, lexical and syntactic data from several contemporary varieties spoken within historical Yemen – within the borders of current Yemen into southern ‘Asīr – with data from Ancient South Arabian, Sabaean, and Modern South Arabian, Mehri, as spoken in the far east of Yemen. On the basis of these comparisons I suggest that Arabic may not have replaced all the ancient languages of the Peninsula, and that we may be witnessing the rediscovery of descendants of the ancient languages.

The Yemeni and ‘Asīri dialects considered are:
Yemen: Rāziḥīt, Minabbih, Xašir, San‘ani, Ġaylħabbān
‘Asīr: Rijāl Alma‛, Abha, Faifi

Keywords: Arabic, Semitic, Ancient South Arabian, Modern South Arabian, lateral sibilants, relative clauses

Kit 438809, Kobashi (Yemeni jewish), turned out fgc3706- but is fgc3708+ and fgc3695- thus breaking up the fgc3708-node. FGC3723 is getting more and more substructured.

Not related to my subclade but nevertheless cool & interesting: a genetic Cohen from Yemen, FTDNA kit 476158, Al-Abdali from Wadi Yahar, عبدالله العبدلي العبادل-وادي يهر , J-Z18271, negative for the downstream SNPs: ZS237, S12192 & Z18290.

Doesn't seem Jewish to me at this point but the sample is very likely of Jewish descent.

Thus IMO it could be very probable that Israelites took part in the Judaization of Himyar.

So we have Levitical Yemeni Jewish samples in Israel that most likely descend from converted Himyarites on the one hand and modern Muslim Arab samples from Yemen that most likely descend from Israelites! Isn't that exactly we want population history to be like? Why simple if it can be complex? :P

I'm quite certain that Yemeni Jews have some Israelite ancestry, in fact I suspect that they are related to the Jewish tribes of Yathrib for instance (the Bani Qurayza were of Kohanic descent for example, so they probably carried J1-Z18271). This individual is probably descended from Yemeni Jews.

Absolutely! Christian Julien Robin wrote in 2004 an essay on that including like you do Yathrib (modern Medina) as a crucial point in the Judaization process of Yemen: Himyar and Israel.

The J-FGC3723 (http://www.anthrogenica.com/showthread.php?10579-J-FGC3723-origins-and-current-distribution/page2) is found especially in tribes of Himyarite Origin. in the year 380 (https://fr.wikipedia.org/wiki/380) AC , King Abîkarib As'ad Converted to Judaism and decided to ban Polytheism from his Kingdom. In the 6th century Ac, religious troubles between yemeni christian an jews were at their summit. King Kaleb the Abyssinian invaded Himyar and put a christian Vassal. After the invasion most of yemeni jews fled the country.

A few new FGC3723+ samples have been added to the map.

Interesting the fact that all these do not stem from the Southwestern part of the Arabian peninsula:

* One sample hails origin from Arcadia in mainland Greece.

* One from the Diyala province of Iraq.

* A few from the Persian gulf area (Bahrain, Qatar and Dammam in KSA).

Going off the contemporary data we are already seeing signs that the Levant was YSC234's diversity hotspot, I expect this to extend all the way back to L862 once we get more ancient data from the Levant.

There are quite a few origin scenarios possible: my ancestor could have been a Yemeni soldier ending up in the Roman army or a Frankincense trader. Just remember that Minaean (Old South Arabian) inscriptions have been on the Greek island of Delos!

The thing is, the Romans tried to bring down the wealthy Yemeni kingdoms but they couldn't after long time. They named Yemen "Arabia Felix", Happy Arabia. I don't think the Romans were able to capture anyone from there.

Maybe your ancestor was a Yemeni soldier enlisted in Sassanian army. Then after some battle, he was captured by the Romans, and assigned as a soldier to serve at the infamous German frontier, or he could have been freed and settled in modern-day Austria.

Also what if your ancestors belonged to the Sabaeans, who migrated to Levant after the great dam was destroyed. The dam's destruction was far beyond repair, so their descendants would become Romans from so on. And remember many Syrians (Syrians, Lebanese, Palestinians and Jordanians in general) were enlisted in the Roman army and fought on several frontiers and even settled after conquests.

Recent archaeological findings suggest that simple earth dams and a canal network were constructed as far back as 2000 BC. The Great Dam of Ma'rib dates back to about the 8th century BC and is considered the oldest known dam in the world, being counted as one of the most wonderful feats of engineering in the ancient world. It is between three mountains, and the flood waters all flow to the one location, and because of that the water only discharges in one direction; and the ancients blocked that place with hard rocks and lead.

Honestly I think that the mass-migration of Sabaeans to the north after the break of the dam of Marib (Sayl al-ʿarim as far as I remember) is Arabic folk lore. From archaeological, linguistic and inscriptional records quite the contrary seems to be true and Arabic speaking people from the north migrated to Yemen. The originally non-Arabic south of the peninsula got more and more arabicized by migrants in the first centuries CE. Eventually it does not account for periods later in history when Yemenis were actively participating in the Islamic conquest and could be found nearly everywhere in the Islamic world.

But this doesn't resolve my lineage's riddle. I personally am inclined to believe that my ancestor was a Middle Eastern soldier moved to the Germanic Limes in order to protect the borders of the Roman Empire and there is no solid proof that he might have been from Yemen. The Yemeni association of FGC3723 is strong though. But again we would need to know the distribution pattern of FGC3723 3200-3000 years ago to make better assumptions.

Sabaeans were not exactly Arabs, as they spoke a separate semitic language (https://en.wikipedia.org/wiki/Sabaean_language).

As for the note, thanks for reminding me of it! Your haplogroup and subclade specifically (J1-Y6370) is a downstream of J1-FGC11. If I recall correctly FGC11 has been found among a 3,700 years old Phoenician skeleton in a burial jar. It is usually thought that the FGC11 lineage formed among early Arabic people (Adnanites), Mesopotamians and Phoenicians after they migrated from Mesopotamia, and they were Arabized in the late periods of Neolithic Era (quoted).

As for the Yemenis, they are mostly under J1-L93 which is much more ancient than FGC11 and it migrated down to South Arabia around 6,000-9,000 BCE.

So I guess the most likely hypothesis for your origins is probably a Syrian soldier from the area of ancient Phoenicia/Lebanese coast, who entered the Roman army specifically from one of the legions: Legio V Macedonica or Legio III Gallica which were based in here and went to a European frontier, and probably continued from there till they reached and settled for once in Austria.

My regards, and good luck! :)

Sabaean isn't South Semitic, it most definitely is a Central Semitic language like all the Epigraphic South Arabian languages (Qatabanian, Hadhramitic, Minaean, Razihi, etc). In fact, there's no such thing as "South Semitic".

Sorry for being a pedant, but I feel this is an important detail which needs to be stressed (as there is a correlation to be found here between the Semitic language tree and J1-L862's phylogeny).

I must have mixed it up with (old) South Arabian. Although on Wikipedia, there is a branch specified as "South Semitic" and it was itself a subset of "Western semitic languages"? And Thanks for the correction!

After many years a new 67 marker match from the Czech Republic has popped up recently at FTDNA. My match carries the German surname Müller. The genetic distance is 7. I only got two 67 marker matches so far. The Roman era migration scenario got a little more weight through this. All my matches (37 & 67 markers) got German surnames and stem from from the Southern part of Germany and Austria.

Important update for my subclade:

After having tested Y700 my Czech match and I went from FGC3706 to FGC3712. The FTDNA haplotree has been updated. The new node downstream from FGC3706 contains 22 SNPs. Still 16 private variants downstream from the new FGC3712 node on average: 11 in my sample, 21 in Müller's sample (isn't that a huge SNP difference?). We have 12 STR differences on 656 STR. I would like to know your suggestions concerning a possible reasonable TMRCA of the European group! I am aware that two samples offer only a limited plausibility. So under FGC3706 there is one Yemeni sample (Al-Rassi), my one and finally the Czech one. I think this could be meaningful for making a first educated guess on the migration period from the Middle East to Central Europe. I attach the Block tree section with my subclade and the updated FGC3723 Haplotree. I would be grateful for your comments or observations. I've been waiting 8 years for something like this to happen! :)

Here's a screenshot of the actual FGC3723 (Yfull J-Y6370 Tree):

Some other user here (Dave-V) suggested this TMRCA for my subclade (but with caution): 600 AD. Sounds reasonable.

FGC3723 TMRCA change in Yfull's latest update:
Everything's back to normal. Most FGC3723 subclades seem to expand in the middle of the second millennium bp. A little later at ca. 1200 ypb the first kingdoms in Southern Arabia begin to appear, we are at the dawn of Southern Arabian civilization. In my opinion this expansion is clearly linked to a big migration from the north:

My closest Middle Eastern y-DNA match Al-Rassi Al-Hassani Al-Qurayshi from northern Yemen (FGC3706+) has got a new y-DNA match from Shibam Kawkaban which is a highly picturesque place that lies 40km northwest of Sana'a.

https://en.wikipedia.org/wiki/Kawkaban

In my opinion FGC3706 could turn out to be a potential Sabaean y-DNA marker. But we'll have to wait for other results and better TMRCAs...

The local Almaqah-temple in Shibam Kawkaban was dedicated to Almaqah ba'l ʿAwwām and is thought of as a daughter temple of the Awwam, the Maḥram Bilqis in Marib.

Hello to everyone. I manage the DNA research for my wife's family. Her brother (David Reininger) just got final result from YSEQ today: SNP J1-FGC3712. Earliest known male ancestor Georges Reininger, born before 1690 in Intzlingen Germany (quite near Basel Switzerland), died in Alsace France, where his family remained until early 1900's emigration to USA. I've joined the FTDNA group for FGC3723 and been in touch via email with its administrator. Very interested to learn more about earlier origins.

Hi everybody, a few updates concerning my subclade FGC3706/FGC3712:

Concerning the origin of FGC3706 (the SNP upstream from FGC3712) we now have two samples from Northern Yemen: one from Shibam Kawkaban the other from Al-Mahwit:

43332

Both cities are only 70km away from each other which is striking as far as the possible origin of my subclade is concerned. My working hypothesis now is that we might come from Northern Yemen.

In addition we got a few new FGC3706/FGC3712 members and we managed to get all Big Y-tested FGC3706-samples to upload their raw data to Yfull.

Yfull delivered a first preliminary TMRCA for FGC3712 which should be refined with the next updates:

https://yfull.com/tree/J-FGC3729/

43334

Now comes the interesting thing: the first calculation for FGC3712 (which happens to be the Central European subclade of FGC3723 with exclusively German surnames) gives us a TMRCA of ca. 650 CE.

This FGC3706 node will be broken up with the next updates. You may get an impression when clicking on the LIVE-version of the tree:

43333

The TMRCA of our FGC3712-ancestor (who might or might not have been the one that migrated from the then Himyarite Empire to Europe) is compatible with the fall of the Himyarite Empire in ca. 630 CE.

I mean this all is still very hypothetical but I begin to question myself if the fall of the Himyarite Empire and the migration of my ancestor could have to do with each other?

Might it have been the reason for leaving what is modern Yemen?

I've read that many Himyarite Jews and Christians left the country with the Islamic expansion.

So far I thought that my ancestor could have been a Himyarite/Sabaean soldier in the Roman army a scenario which I won't discard until we have better data.

What are your thoughts on this?
