Here is a site with Vernon Co., MO information. http://www.rootsweb.com/~movernon/ This is the site about the plat maps: http://www.rootsweb.com/~movernon/vcinfo.html *** last year when I was back there (Nevada, MO) the 3 plat books there were selling for: 1876 plat book sold for $7.00 the 1886 plat book sold for $5.00 [both of these books are about 8" x 12" , and each township is on seperate page.] The 1903 plat book now sells for $20.00 is about 12" x 18" much easier to read and it has a index with names of land owers in. It also has a map of the layout of the towns***
