Welcome to Iowa Genealogy Trails!

Volunteers Dedicated to Free Genealogy

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.

This county website is in need of a permanent host.

If you are interested joining our group as webmaster for this website, or any of our websites,
view our

Volunteer Information page.

A desire to transcribe data and know-how to make a basic webpage is required.
