Welcome to the Johnson County Genealogy site! My name is Cindy Booth Maher and I am the Coordinator for Johnson County. Hopefully you will find this site to be helpful as you do research of your Johnson County roots.  We have many genealogical resources available here, just click on the links to the left.

Johnson County has wonderful support from the Iowa CIty Genealogical Society. Because of their contributions and the contributions of other generous volunteers, this site contains a large volume of information relating to the genealogy and history of Johnson  County.

We would be appreciative of any contributions you would like to make to this site. Please contact me with any contributions or suggestions you may have. Feel free to visit often to see what new content has been added.

Always remember that all of our content and information here is free, and has been put together by volunteers for you to use in quest to find your family histories.

WWI 1914-1919

Johnson County Iowa is located in the fourth tier of counties north of the Iowa-Missouri line and in the third row west of the Mississippi River. It is bordered on the north by Linn, on the west by Iowa, on the east by Cedar and Muscatine and on the south by Washington and Louisa counties. 

The boundaries of Johnson County were fixed and approved 21 December 1837 according to the laws of Wisconsin Territory of which Iowa was then a part.  The county was organized in the fall of 1838 following authorization of the newly organized Territory by Governor Lucas.
