Chaim Kadezky 1904 ship manifest

On November 16, 1904, Chaim Kadezky (35 yo and single) arrived at Ellis Island on the Oscar 2. He last resided in Russia. He joined his brother S. Kadetsky living at 709 Columbus Ave, NY.
At that time Sussman Kadetsky lived at 709 Columbus Ave. He lived there from at least 1900 through the 1920s. Sussman's relatinship to the other NY or MA Kadetsky is still unknown. But his siblings his nephews and sister in law all lived in sierpc where Pessia (Kadetsky) Lelonek and Chaskiel Kadetsky lived from 1900 until WW2. So maybe the connection of the families lies in Sierpc. Anyone know?
