Harry Morris Warner was born in Krasnosielce, Poland, the son of Benjamin Warner and Pearl Eichelbaum. (Harry Warner always listed the Americanized name of the village, Krasnashiltz. In 1881 Poland contained three villages with that approximate spelling; Warner probably came from the one in eastern Poland. ) Benjamin Warner, a poor cobbler, immigrated to the United States during the 1880's to escape persecution as a Jew. He sent for his wife and four children sometime between 1887 and 1890. The family first settled in Baltimore.
