I have searched the index for many names that were not there. I knew them to be dead, with ss#s, and no one collecting any benefits from them. It was my understanding from what I had read about this index, that any death benefit issued for a social security number holder would be included on the list. I would be curious to know why so many are missing from this index. Does anyone know if it would do any good to notify the SSA about these omissions? This is a valuable genealogical research tool. It would be nice if it were complete.
