Do you know the difference between the warrantee and the patentee when searching the Bureau of Land Management website? The patentee generally was the person who settled the land and acquired title to it. The warrantee was the person to whom a “coupon” or warrant was issued. This warrant was good for a specific acreage of land in thee federal territories.
Some warrant holders sold them to other individuals who actually acquired went to the federal domain, struck out a claim and received title to federal property.
Always search for warrantees in all states. If your ancestor assigned his warrant to someone else, that patent location may have nothing to do with your ancestor at all.
