The records in Record Group 4 fall into two main categories -- those relating to jurors, and those relating to the operations of the Surrogates Court in Westchester County. The jury-related records primarily cover the late-19th and early-20th century, while the extensive Surrogates Court records provide researchers, including family historians, with access to estate papers and wills from the late-18th century through the mid-20th century.

Administration Letters, 1787-1940
Series 168
22 v. Arranged chronologically. Indexed by: Series 171.

Records of estates which are intestate, are being contested, or those containing dependent family members. These letters document the transfer of legal responsibility for paying taxes, care and custody of dependent family members, liquidation of debts, and transfer of property to the heirs as effected by an administrator appointed by the Surrogate Court. Letters of Administration grant authority to administer the entire estate of the deceased without restriction; Letters of Administration de bonis non (1852-1935 only) appoint an administrator to complete the settlement of an estate partially settled by another administrator; Letters of Temporary Administration (1853-1940 only) order an administrator to produce an inventory of the deceased's estate within three months; and Letters of Administration with Will Annexed appoint a new administrator to act on behalf of executors who refuse to do so.
