I am trying to locate missing heirs of an individual. I have their death certficate which only has their date of birth, death, ss# and residence when they died. The funeral home and cemetery had no additional info for me. I do know that the social security # was issued in Washington. I called the SS office and they told me that they might not have the ss application (the guy was born in 1930). Any suggestions on what I should do next? Thanks
