Thanks,
I ask because a comment brings in a mention of the Katzenellenbogen lineage.
J-L823, (8-2-3), has been found to comprise the genetic signature for the Katzenellenbogen rabbinical lineage, per work by Paull, Rosenstein, and Briskman:

My mtdna is now updated by FTDNA as: J2a1a1+16261+215
With only 4 close matches in Algeria, Spain, Portugal and England. I am close to the guy's mum below. I think! I am related to the Henrique de la Fuente family but most were wiped out in Holland so I never get an exact match. We came over to UK in 1700s. Anyway. I'll keep trying to find my family..
