Am looking for descendants of all Beckermans or Beckermanns who lived in NYC (Manhattan, Bronx and Brooklyn) circa 1850 to 1920. Ancestors came from Hanover, Bremen, Hamstdat, nd Berlin. Have extensive data - looking for more input - willing to share data. Known interrelated familiies include Eberling, Burns, Quillan and Beglan.

I am looking for Beckermans in NYC at around the same time. My Beckerman's intermarried with O'Connell's. Are we looking for the same family?
