Federal Land Patents
Follow
the link below and click on the "Search Land Patents" tab to access
free copies of Federal Land Patents. You can view the legal description
and download a free copy of the record. It works for all states, not
just Indiana. I found it works best with just a last name, and it
sometimes helps to vary the spelling. This can be a really helpful
tool.
