The Surrogate's Court in each county generally has records dating back to the establishment of the county or 1787, whichever was later. Record keeping was systematized by an 1830 statute. Surrogate's Courts maintain records of wills, letters testamentary, letters of administration, orders and decrees, and appointments of guardians; and filed papers, including original wills, petitions for probate (gives date of death and lists next of kin), performance bonds, property inventories (seldom found after ca. 1900), administrator's or executor's accountings, etc.
