you give me two last names of the immigrating parents and it stfrrikes as odd that the death certificate only had LAST NAMES but no FIRST NAMES which you need to locate the information about the ;parents inorder to continude your research. Where did these people comde to the USANY or some other port lik Boston or Phildelphia it would also be helpful to know.
For your information there are THOUSANDS of immigrants surnamed Marino and Spagnoloentering the USA at NYC ellis island alone!!!! Get back after you really dio your homework. a Hometown name in Italy would cinch it!. Petertimber
