I am looking for a Joseph Einbinder who enlisted in the Spanish-American War as John Cooper. I have no idea why he changed his name. John Cooper married Della Socket or Sockett and had five children. He died before 1952. I am guessing he would've been born in 1879 or 1880. I did find a John Cooper born August 12, 1879, and died June 1948 in another database, but I have no idea if that is him. I think the name Einbinder is Polish, but I am not sure. I do know he was Jewish. Any information on him or a history of the name Einbinder would be GREATLY appreciated.
