Sing Sing Admission Registers
The State Archives holds inmate admission registers from Sing Sing Prison for the period circa 1870-1970 (Series B0143). Inmate entries are recorded chronologically. The registers are not indexed by inmate name.
Information in inmate entries varies over time, but generally includes criminal history and basic personal and family data.
Census data is not sufficient to locate inmates, except for the 1940 U.S. Census, which lists prisoners' inmate identification numbers. To search, researchers must provide the date of conviction and/or admission, or the inmate identification number.
The Archives holds no Sing Sing inmate case files (except files of some inmates who were executed). Admission registers are the best available source of inmate data.
