Delaware Probate Records
Probate records have been kept by the register of wills in each county from 1682 to the present. The Family History Library has probate indexes and records for all three counties, including wills, administrations, and guardian accounts to about 1850. Most of the original records are at the Delaware Public Archives.
Published county court records for the 1600s refer to many probate matters. These can be found in the Library Catalog Place Search under DELAWARE, [COUNTY] - COURT RECORDS
Wills, administrations, and guardian accounts to about 1850 are frequently listed in Orphans' Court records. A statewide index has been prepared to the year 1800:
