Welcome to Jefferson County, Missouri

Our goal is to help you track your ancestors through time by transcribing genealogical and historical data and placing it online for the free use of all researchers.
We're looking for folks who share our dedication to putting data online and are interested in helping this project be as successful as we can make it.
If you are interested in joining our group by hosting either this county website or one of the available county websites

This county website is in need of a permanent host. Until this site has a host there is no one to answer your research questions.
If you are interested joining our group as webmaster for this website, or any of our websites, view our Volunteer Information page and Email Kim.
A desire to transcribe data and know-how to make a basic webpage is required.

We'll be adding data to this site as we can.
You can help us to get this site growing by sending in your family's data.
