This question already has an answer here:

I just recently learned that there are still Kohanim, members of the priestly family of Aaron, alive today. I had thought, mistakenly, that they had vanished with the destruction of Herod's temple in 70CE.

My question is, how do the remaining Kohanim know that they are in fact descendants of Aaron?

  • Thanks for the vocabulary update, @Loewian. Jewish terminology isn't my strongest attribute :) – Dan Gayle Feb 11 '16 at 1:06

They have a tradition from their patrilineal ancestors. See also: https://en.wikipedia.org/wiki/Y-chromosomal_Aaron

  • As Jews, a lot of us have family tradition about which tribe or family we are from; however, are we to rely on a family "tradition", whose member(s) might be interested in whitewashing certain facts about the family line? I ask this in relation to the 9-kohen-related mitzvoth (from the 77 positive and the 194 negative mitzvoth) that are still valid for today. Basically, based on your answer, which is a common answer among those of us, who follow Jewish tradition, it is really a matter of trust that so-and-so is a Kohen, because he believes firmly from his family tradition? – ninamag Aug 28 '17 at 15:11
