Hi
I have recently found a record of a Kisrel Borenstain age 24 emigrated to Argentina in 1932. He originated in the town of Lopuszno. His male descendants would be kohanim.
I am certain that this man is related to my Bernstein/Borensztajn family from the same village in Poland. If anyone know of this family in or around Buenos Aires, I would appreciate help in getting in touch with them.
