The Douglas County Recorder of Deeds have records of all land transactions back to 1886.  Earlier land transactions may be on file if the parties re-recorded the transaction after the courthouse fire of April 1886. The following sets of plat maps exist:
 

1846-47 Survey Maps -- A few surnames were recorded on this earliest survey map.  A copy is on file in the Douglas County Museum.

• In the 1840s, the Federal Land Office in St. Louis, Missouri, contracted with independent surveyors to go
  through the entire area that included present-day Douglas County, Missouri.  As the surveyors completed the
  field work, they laid out the legal townships, ranges, and sections that have been used since that time to
  assign land title. 

• No legal claim to Douglas County land was documented prior to the completion of these
  surveys.  (According to Bessie Selleck, in her 1952 book, "Early Settlers of Douglas County," Sarah Lawrence
  was the first homesteader in Mar. 3, 1847.  Her land parcel was in Twp. 25 - Rng 18.  Using the map below,
  one can see that Sarah Lawrence's was in the extreme southwest corner of the county).

• As the surveyor conducted his work, he prepared maps that showed roads, streams, mills, and the surnames of any residents he discovered along the way.  Click Here to see a listing of the surveyor's notations listed by township, range and section.

1886 July Plat Maps.  {prepared by the Federal Land Office in Springfield, these plat maps show the original land patentee for each parcel as of July 1886.  The maps are indexed.  A set of the maps can be acquired from the Douglas County Hist/Gen Soc.

• In 2004, a set of old plat maps was discovered in a vault in the Douglas County Courthouse (by yours truly).  Apparently, they were created by the Land Office in Springfield, MO, after the Douglas County Courthouse fire of April, 1886, which destroyed most county records including all land records.  With these plat maps, the county was able to begin its land records system again. These 1886 plat maps show the person to whom the U.S. Government issued each parcel of land as of July 1886.  (The maps DO NOT show subsequent land holders to whom the original owner might have sold the land before 1886).

• Prepared by hand back in 1886, these maps show the original land holder's name, the date of the acquisition, an indication of the type of acquisition and then a reference number.  The plat maps indicate three ways in which these early settlers acquired land: (1) by "proving up" a homestead, (2) by land warrants (issued to veterans), or (3) by cash.

• Cost: $15.00 + $2.00 shipping.  Send orders to the Douglas County Historical and Genealogical Society, Inc.  P.O. Box 986, Ava, MO 65608.

ca 1930 Plat Maps -- These plat maps with indices, shows the land holders in the 1930 just before modern roads came to the area.  A set of the maps can be acquired from the Douglas County Hist/Gen Soc.

• A few years ago, Nancie Todd Weber prepared a fully indexed set of plat maps (circa 1930) for the Douglas County Historical and Genealogical Society.  This publication is a 'must-have' for any serious researcher of Douglas County history and/or families.  (Click here to see how to acquire this publication). 

• The University of Missouri has placed 1930 plat maps online that appear to be the same ones (without index) as those of Nancie Todd Weber.  (Click here to see those online 1930 maps)

• In the 1920s, the current state highway system was not in place.  Besides showing all the land holders in
  the 1920s time period, the maps show some of the old roads that our ancestors used.
