I've already talked a lot about the possible familial connections of the Seleucid Dynasty in my three part Genealogy of The Antichrist study.
In light of my recent speculation that the Eight King could be Antiochus Epiphanies himself. As well as my other speculation that The White Horseman could claim, validly or not, Ephraimite descent and try to claim he's Messiah Ben-Joseph. This is an interesting speculation.
As I said before, I don't think he'll admit to being the hated Epiphanes, I think it's possible if he is open about being someone from the past, he might claim to be his more fondly remembered father.
I do not necessarily endorse Lost Tribes became Western Europeans theories in general. But the nature of tribal migrations is complicated. And Dan certainly had an interesting history. Also my theory is more about him claiming such a lineage then if it's actually true.
Antiochus Epiphanes is not usually someone advocates of such theories seek to claim. But I have a different perspective.
The Macedonian Royal family claimed descent, like the Spartans, from the sons of Herakles and through him to Perseus and Andromeda of Joppa and the Danoi. All allowing possible connections to Dan or Edom. But the Seleucids have no provable direct connection to the Agrid line however.
The sons of Herakles whom the Spartan and Macedonian royal families claim descent from supposedly intermarried with the leading family of the Dorian tribes. Some engaged in Lost Tribes related theories have speculated that the Dorians could have a connection to Dor, a port city of Manasseh, one governor of Dor had married a daughter of Solomon. Dor is also associated with the Tjekker of the Sea Peoples.
The Macedonians were distinct from the other Dorian derived classical Greek nations in also having some Celtic stock to them. So Oliver Stone was not being completely random casting Irish and Scottish actors as Macedonians in his Alexander The Great film. The relationship between the Celtic and Cimmerian peoples is complex.
Apama the wife of Seleucus I was the daughter of Spitamenes, a Perisan Satrap. He had in his ancestry Persian and Median rulers and through them Assyrian ones too. The mother of Esarhaddon was possibly an Israelite. Further back there were Assyrian Kings named Asshur-Dan about whom we know little, making me wonder if connections between Assyrian Royalty and the Denyen might have taken place.
The City of Antioch itself is pretty much in the heart of the Danuna/Laish Dan area.
The Crimmerians are at the center of the main Lost Tribes became Europeans theories. Most critics of the view just point to the obvious connection between the Cimmerians and Gomer son of Japheth, that Bill Cooper documents well in After The Flood. He covers it in both the Where to Begin chapter and Appendix 3.
Thing is, the name Gomer also appears in Hosea as the name of the prostitute God has Hosea marry who becomes a symbolic type of Ephraim/Israel. So advocates of the theory suggest using that name could also be a prophecy about a future intermingling of the descendants of Gomer and the Northern Kingdom.
Khumri is how the Assyrians rendered the name of Omri, which they used to refer to the Northern Kingdom in general even well after the House of Omri fell. The basis for connecting the northern Kingdom exiles to the name of the Cimmerians has often been just based on arguing that Khumri could've become Ghumri and Gimri and so on. That I think is largely what makes it look silly to people. Though more implausible things have happened in etymology.
Our pre-history of the Cimmerians is pretty speculative, drawing mainly form Herodotus and other heavily contrived Greek accounts. But a connection between their name and Crimea I do consider likely.
The first appearance of the Cimmerians in Assyrian records is during the reign of Sargon II, dated to about 714 BC. After the first two main deportations of the Israelites. At this time they seem to be "In the midst Mannae" a buffer state between Assyrian and Uratu, rather then where they usually were later. They assisted Sargon in his war with Uratu. Mannae is mentioned in The Bible as Minni in Jeremiah 51:27. Their kingdom was located south and east of Lake Urmia. Firmly within Median territory where many exiles had been taken according to II Kings 17:6.
Later the Cimmerians during the reigns of Esarhaddon and Asshurbanipal would become enemies of Assyria, and ally with other traditional enemies of Assyria. It's not implausible that descendants of exiled Israelites would have been attracted to joining up with the Cimmerians.
The Cimmerian nation at it's greatest extent expanded into many other regions of Turkey, like Pontus and Cappadocia. In Hellenistic times the Cimmerians who remained in the region were known as the Galatians. The Hellenistic kingdoms of Galatias, Cappadocia and Pontus royal families intermarried a lot with the Seleucid Dynasdty, as well as Pergamon and Commagene. The mother of Antiochus IV Epiphanes was the daughter of Mithridates II of Pontus.
