I can’t nor do I have the resources to prove it, but I am sure I saw on the news quite a few years back that Israel was not letting them into the country because DNA tests showed they were not related to Jews.
Of course I think one can be converted to Judaism, not that I am up on that either.
I also recall Israel basically bowing to world pressure and letting them in, also quite a few years back.
Assuming they are Jewish by blood, instead of conversion, perhaps either males or females from Israel, many years ago, intermarried with Ethiopians. Therefore, neither the maternal or the paternal line should match. The autosomal DNA would be the way to go, except it is generally good for just hundreds of years of ancestry, not thousands. So, this is a case, where DNA may not help prove. I may be wrong in my understanding, but have read a bunch in past few months (as I had all my lines tested).

Israel did not bow to world pressure; Israel initiated this airlift and subsequent airlifts of Ethiopian Jews.
I remember reading about this at that time.
This was PROBABLY a story about LAMANITES...
Anyone can convert to Judaism. I did 9 years ago.
