Bureau of Land Management - General Land Office... 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).
The Bureau of Land Management Office tract books are a good source for additional information on your homesteading or federal land acquiring ancestors. This material supplements what is in the homestead file, allows you to see names of neighboring claims, even if those claims were not completed. If you've ever wondered who might have started a claim near your ancestor, but never completed it--these books are the way to find out.
