Does the tribe of Levi still exist?

Answer 1

Yes, the tribe of Levi, like the smaller Levitical family of the Cohanim, still exists. There are are lots of people who have the surnames Levy, Levi, Lev, Levitan, Levitas, Segal, Cohen, Katz, Kahn, Kahan, Kagan, etc. who are still identifiable as part of that tribe.

Answer:

The Tribe of Levi has the distinction of being the only one which is clearly identifiable today.

The great majority of Jews today, some 80% or so, are descended from the tribe of Judah (plus converts and descendants of converts). The remaining 20% include Levites (from the tribe of Levi), Cohanim (also a part of the Levites), the entire Tribe of Benjamin, and a small percentage from every one of the remaining tribes. (When the Ten Tribes were carried off into Assyria and didn't return, a few of them had already mixed into the tribe of Judah before that, through marriage. Also, the Talmud relates [Megillah 14b] that, one century after the Ten Tribes were exiled [and their location was still known], Jeremiah journeyed to where they were and brought some of them back to Judea. Thus, today's Jewry includes a small percentage of every one of the Lost Tribes. See for example the Talmud, Pesachim 4a.)
