Rosenfield, Eisenberg, Lewis and related Families Home Page

I am researching the families related to members of the Rosenfield, Eisenberg and Lewis families who were members of the REL Family Circle. These families lived primarily in Brooklyn, NY, Minneapolis, MN and, eventually, as is common in middle class Jewish families, the Miami, Miami Beach, Fort Lauderdale areas in Florida.
Presently I have some 1300 individuals in the family tree, although the information I have for many of them is minimal. Any help will be appreciated and, of course, I am willing to share what I have with anyone contributing or even interested.
