This answer is a long time since you posted and I am not sure of how correct I am. My mother is Eleanor Anne Kessler and her father was Sam Kessler. He had three siblings: Rae Stein (I’m assuming your side) Sarah, and Henry (I think). They lived more towards the Bronx and and Westchester.
Also, I recently had my DNA tested with indications that we are 2nd or 3rd cousins :)
