Maps are an interesting tool, not only do they tell you where your ancestor lived, they show you how they got there!! Imagine the hardships they endured in their travels.

BLM, GLO Records We provide live access to Federal land conveyance records for the Public Land States. We also provide image access to more than two million Federal land title records for Eastern Public Land States, issued between 1820 and 1908. Images of Serial patents (land titles issued between 1908 and the mid-1960’s) are currently being added to this web site. Due to organization of documents in the GLO collection, this site does not currently contain every Federal title record issued for the Public Land States.
