A review of the land records to determine the ownership and description of the property. The history of a property’s title (“chain of title”) reveals all parties who have a legal interest in the property and the nature and degree of their interest. Land records are registered and maintained by county recorders. They generally have indexes to sellers (“grantors”) and purchasers (“grantees”). Deeds usually do not provide many details of structures on a property, but can provide clues as to when property was sold or purchased, divided or developed, and possibly when buildings were erected. The researcher must know names of owners of the property.
The University of Delaware Library has copies of deeds for New Castle County through approximately 1850 on microfilm, as well as grantor and grantee indexes (Microfilm S 334, Microfilm S 334.1, and Microfilm S 334.2).
The New Castle County Recorder of Deeds office has land ownership records for New Castle County. The documents on file in the New Castle County Recorder of Deeds office date back to the 17th century and include such historical items as the land grant assigning William Penn the area that has become the State of Delaware.

National Register of Historic Places
The National Register of Historic Places, including more than 71,000 listings, is the Nation’s official list of cultural resources worthy of preservation. The National Register Information System (NRIS) is the official database of the National Register of Historic Places. You can look up historic places by state and county. The information you retrieve, however, is minimal. An alternative to the online Register, you can also check the printed National Register of Historic Places (Ref E159 .N34), but the latest edition in that of 1994. After you determine that a property is on the National Register, you may be able to use the following resource.
