There hasn't been much effort by Christians who hold to a Biblical model of history and genetics to identify the Table of Nations in Genesis 10. One person who has is Richard P. Aschmann who roots his tree on the identification of J1 y-dna with the Jewish Cohenim descended from Aaron and that E-y-dna with Ham because of its presence in Africa. However if he is wrong in these two identifications (which I believe he is) then his understanding of the y-dna tree and its connection with the Table of Nations will be false. Aschmann uses the ideas of Leif A Bostrom for his understanding of the y-dna tree.
Others have claimed that J y-dna is the Israelites haplogroup and I y-dna are the lost Tribes. Others that R y-dna is that of the Tribes of Joseph wth R1b as Ephraim and R1a as Manesseh and the Jews and Arabs are IJ y-dna. Others hold that R1b are the Israelites and R1a are the Edomites. However many of these people have not tried to fit the entire y-dna tree into their identifications.
In regards to J1 y-dna Bostrom and Aschmann's logic is if the dna marker of the Jewish Cohenim is J1 then Aaron must be J1 y-dna and thus all Israelites must be J1 y-dna. It is clear that not only do some Jewish Cohenim have J1 y-dna but so do the Arabs and especially Mohammed's family and his descendants, so do the Samaritans and many other Jews who are not Cohenim as well as many Greeks and Italians. There are other groups of Cohenim who are not J1 y-dna and there are two distinct clusters of R1b Cohenim that can also make a serious claim to being descended from Aaron. Also E y-dna is not from Ham as it is linked with D y-dna which has no African connection. DE are the descendants of Japheth. Most other researchers would agree with me that F is Shemite and I believe F,C is Shemite. Thus this leaves only A and B who both happened to be in Africa and thus are the Hamite haplogroups. However Aschmann and Bostrom believe that F is Hamite.
The problem with many of these identifications is they try to link modern Europeans to its post flood population of Japhethites. This was first accepted by both Jewish and Christians writers who sought to link the nations of their own day with the Table of Nations. Unfortunately they didn't take into account that the Japhethite names given for different parts of Europe had been depopulated of their original Japhethite inhabitants and the names used by the new inhabitants descended from Shem after the Ice Age ended. Genetic research demonstrates that Europe's population is very different today from earlier times. In fact after the Ice Age ended in Europe Shemite peoples of F (the Black Hebrew sons of Joktan) and C1 (the Black Shemites of the sons of Charran) as well as I y-dna (Dark White (Tan) sons of Ishmael) entered Europe.
The only Japhethite population of any significance in Europe today is E1b y-dna (Javanites) who returned later after the Ice Ages. E-V13 y-dna (around 200 BC) is the marker of the Greeks who descended from the southern Atlanteans (E-P2 y-dna) who ruled southern Europe and Northern Africa. Many more Atlanteans spread into Europe and Africa with the sinking of their homeland in the 10th century BC. The spread of E-V13 y-dna (descended from the Rodanim or Dodanim clan of E-V68 y-dna) from Greece occurred during the time of the Greco-Roman Empire. The Atlantean Philistines were the Kittim (E-P2, E-Z827) who are also the so-called Natufian culture found in Israeli archeology. Just as earlier the southern Atlanteans had pushed many of the remnants of the Tribes of Gomer, Tiras and Ashkenaz into Africa so after the sinking of Atlantis the Rodanim of Atlantis (E-V68) pushed many of the tribes of Tarshish (Spain) of E-M2 y-dna, Elishah (southern Germany/northern Italy) of E-M329 y-dna and Kittim (Italy and Cyprus) of E-Z827 south into Africa. The Tribe of Ashkenaz of E-M44 y-dna settled in northern Europe. One branch of this Tribe moved south into North Africa and another moved east across the Russian steppes (E-Z17699) into Asia where they may have converted to Judaism and joined the Jewish people. They gave their name to the Jews in north eastern Turkey called "Ancient Ashkenaz" that may have joined the Khazar Empire. The Druze may have been a southern migration of these "Ashkenaz" Jews which had the real Ashkenaz as a small percentage among them.
However Aschmann reads the tree in a much more radical way than I do and sees IJK as Noah whereas I believe this is Abraham. He then believes that IJ is Shem and K is Japheth and that the tree upstream of IJK is in fact the Hamite branch. My own belief is that CF on this chart represents Noah and thus CT is in fact AB and represents Ham. Bostrom sees F as Ham.
Leif A Bostrom's y-dna table
I will now discuss some other possible scenarios held by others and how they would connect to the y-dna tree. If J y-dna represents the Jews and I the Lost Tribes then IJ will represent Jacob and K will represent Esau or Edom. In this case the Lost Tribes will be descended from the I1 y-dna Vikings (Joseph Tribes) and the I2 Sarmatians (other Tribes). In this scenario most of Asia and Europe are thus Edomites. Then IJK would be Isaac and H Ishmael and HIJK Abraham. One would then need to fit this model with all the other nations.
Another scenario would be for IJ to represent the Jews and Judah and K to represent the Lost Tribes and thus IJK would represent Jacob in this model and H Esau. This would mean that the Vikings and Sarmatians of I y-dna could be the Judah-Zerahites. Then HIJK would represent Isaac and G Ishmael. Thus GHIJK would be Abraham in this scenario.
The British Israelites hold that Britain is to be identified with Ephraim and thus Ephraim would need to be the Gaelic R1b L21 which I believe is the y-dna of the Davidic House of Nathan. If this British Israel scenario is correct then the Tribe of Manasseh would be the Saxons (R1b DF19), the Franks (R1b U152) and the Spanish (R1b DF27). Thus R1b P312 would represent Joseph and R1b U106 the Leahite Tribes including Judah. In this scenario Jacob would be R1b L11/P310 or L51, Esau R1b Z2118 or Z2103, Isaac as L51 or L23, Ishmael as Z2103 or PF7562 and Abraham as R1b M269. Thus R1b would most likely in this scenario be Heber and R1a Joktan.
However if R1b P312 is Ephraim then U106 would be Manasseh and thus R1b L11/310 and L51 would represent Joseph and the other Lost Tribes while the Jews and Judah would be R1b Z2103. This may also see R1b as Jacob, R1a as Edom, R as Isaac and Q as Ishmael and thus P would represent Abraham. Thus K would represent Heber and IJ would be Joktan.
Another scenario which is popular with some is that R1b is Ephraim and R1a is Manasseh and thus R represents Joseph. My own theory holds that R1a is Joseph and thus Ephraim is found among the Slavic peoples and Manasseh the Turkic. R1b is the marker of the Tribes descended from Jacob via his wife Leah. Thus in my scenario IJ represents Ishmael.
Over the last 10 years I have been researching on the tribal identifications in connection with genetics and also studying archeology and history in the light of a Biblical model of about 4,500 years of post flood history. I have had to change my ideas many times over this period due to more discoveries and studies. It is still a work in progress and probably always will be but I think this basic identification of the Table of Nations in Genesis 10 to be settled and most likely. However I am always open to the ideas of others if they can situate their identifications into the bigger picture of the whole genetic tree.
