You can find the patent deeds for the FIRST TIME the various and tracts were sold on the internet from the Bureau of Land Management. Site is free. You can printout a copy of the original patent - very impressive. Contact me here again if you want the URL.
Subsequent sales of the various tracts are not, to my knowledge, available on-line. Go to the courthouse in Paris for this.
You can order a book of CURRENT plat maps (2011) for Edgar County by contacting the Edgar County Farm Bureau at:
www.edgarcountyfarmbureau.org. Very useful 75 page booklet and it will tell you who owns every piece of land in the county in 2011. They're not expensive.
