While browsing in the EJ, I came across an article on Rabbi Isaac
ben Samuel Ha-Levi (1580-1646?) who was the older brother of the
famous Rabbi David ben Samuel Ha-Levi. Is anything known about the
descendants of Rabbi Isaac?
I was particularly intrigued to see that Rabbi Isaac wrote a book
called 'Beit Ha-Levi". The Brisker branch of the SOLOVEICHIK family
call themselves 'Beit Ha-Levi" and I wonder if this could be because
they are descended >from Rabbi Isaac. It is interesting that, over
the generations, 'Isaac' has been one of the most popular names in
the SOLOVEICHIK family.
