So a Messianic Jew showed me a passage from a part of acts saying that they were called "Christians" at such and such a place and time
He said that they were calling them Christians as an insult although the text does not say that it was an insult just that they called them Christians
He insisted the proper title for him is a Messianic Jew and not a Christian because Christian is an insult
It does not say in the New Testament that they were called Messianic Jews though
They would have stopped tracking their ancestry because the followers of Jesus did not view themselves as being superior because of their Israelite ancestry and were not racist about it
On the other hand the ones who rejected Jesus believed they were superior because of their ancestry and won over converts who had no or only trace biological ancestry from Israel
These descendants of these converts became very racist even though they had less biological ancestry

So I suspect that if the Bible is historically accurate than the original Israelites were of Syrian ancestry
And if I am to add on some other assumptions
I suspect that the followers of Jesus who were of Israelite ancestry stopped tracking their genealogies but many people in the Church of the East ( as well as possibly other Churches in the middle east ) are biological descendants of Israelite who were followers of Jesus
Church of the East has liturgy is in Syriac
