Searching for birth sibling born June 5 or 6, 1951 at Touro Infirmary in New Orleans, La. Birth mother was from Mississippi. I have signed up at the Louisiana Reunion Registry. The State advised that my sibling has not signed up the the Registry, but also did not mention the non-id information in the return letter. Would the non id still be at Touro today? Where do I turn to locate that information? Any help would be appreciated. Thanks,
