"Federal Land Patents offer researchers a source of information on the initial transfer of land titles from the Federal government to individuals. In addition to verifying title transfer, this information will allow the researcher to associate an individual (Patentee, Assignee, Warrantee, Widow, or Heir) with a specific location (Legal Land Description) and time (Issue Date). We have a variety of Land Patents on our site, including Cash Entry, Homestead and Military Warrant patents."
"Survey plats are part of the official record of a cadastral survey. Surveying is the art and science of measuring the land to locate the limits of an owner's interest thereon. A cadastral survey is a survey which creates, marks, defines, retraces or re-establishes the boundaries and subdivisions of Federal Lands of the United States. The survey plat is the graphic drawing of the boundaries involved with a particular survey project, and contains the official acreage to be used in the legal description."
"Field notes are the narrative record of the cadastral survey. They are written in tabular format and contain the detailed descriptions of entire survey process including the instrumentation and procedures utilized, calling all physical evidence evaluated in the survey process, and listing all of the individuals who participated in the work."
