That's not correct. Among the tribe of Levi, only the Kohanim were allowed to touch the temple furnitures. They were the son of Kohath, and God chose them out of the tribe of Judah to be responsible for the Tabernacle furnitures. So the modern day "Cohen" have a identifying Chromosome that identifies their clan. Thus, when temple worship is re-established in the next re-built temple, the Cohen will be the priests in charge of the Temple articles: The Candle Stick, table for shewbread, the trumpets, the priestly robes, the altars of sacrifice and incense, the lavers, the anointing oil, the incense, and the wash basin.
Some folks with Russian Jewish roots have told me there are extensive Jewish family genealogies going back to Medieval Spain that are still maintained, and that there may be others going back to the time when the Temple practices were still active.
You may know more on that. However, even the Welsh have genealogies that can go back 1700 years.
and God chose them out of the tribe of Judah LEVI...
