Maps of Missouri are an important tool when it comes to ancestral and family history research, particularly in the event that you live far away from where your ancestor was living.
Since Missouri’s political boundaries have sometimes changed over the years, historic maps are essential in helping you discover the exact location of your ancestor’s home, what land they owned, just who their neighbors were, and much more besides.
Maps of Missouri are an excellent resource for starting out with your own research since they provide factual information quickly and in an easily understandable format. The National Archives holds ward maps of Kansas City and St. Louis.
States bordering Missouri are Arkansas, Illinois, Iowa, Kansas, Kentucky, Nebraska, Oklahoma, and Tennessee. Missouri’s 10 largest major cities are Kansas City, St. Louis, Springfield, Independence, Columbia, Lee’s Summit, O’Fallon, St. Joseph, St. Charles, and St. Peter’s.
