Much of eastern Oklahoma passed by Indian allotment rather than by homestead patent, so it will not appear in BLM's General Land Office records at all. Title for trust and restricted allotted land is recorded federally with the BIA Land Titles and Records Office, which is a separate system from both the county clerk and BLM.
Almost every Oklahoma description ends in I.M. or C.M., and that suffix is not decoration. A T2N-R5E in the Panhandle is entirely different ground from a T2N-R5E under the Indian Meridian. If a description reaches us without the meridian and the county is in the Panhandle, we go find it before we do anything else.
