Census records purged?
Why not. Seems his Columbia and Harvard records have.
Wouldn't know that for another 22 years since they are not released to the public until 70 years after they are taken.
Census Records for 1960 will not be released until 2035. The records for 1930 were just recently released.
FYI, federal census records are only made available to the public 72 years after the census was taken. Currently then, the latest federal census records available are from 1930 - not of any use in this investigation, unfortunately.
