The information in this database was compiled from the book, "Official Manual of the State of Missouri for the years 1919-1920" compiled by John L. Sullivan, Secretary of State, (no publisher or publication date is given). This book contains a listing of over 25,000 state and municipal employees of the State of Missouri for the years 1919-1920. The listings include employees of various state institutions and municipal governments down to the city levels. There is also a listing of the Republican and Democratic Committees (mens and women) to include almost 2,600 women in the first year women were allowed to vote. There are also mini biographies of most of the senators, representatives and federal government offices (these are designated by a plus sign [+] next to the first name). The military includes the National Guard officers that served during World War I. Since this book covers a federal census year it is an excellent source in locating information on a person.
