Land Records can be a valuable source once you have established that your ancestor lived in the area.  A search of courthouse records can bring surprises.  Many old deeds have all kinds of records attached to them.

DNR Land Records, Public Land Records

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.
