Welcome to Lake County Illinois History and Genealogy Presented by Illinois Genealogy Trails a part of Genealogy Trails Volunteers Dedicated to Free Genealogy This Site is Available for Adoption Many thanks to our former host, Anne Kunzen, for all her hard work on this site! Our goal is to help you track your ancestors through time by transcribing genealogical and historical data 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 it can be. If you are interested in joining Genealogy Trails, view our Volunteer Page for further information and then contact Kim. (Enough knowledge to make a basic webpage and a desire to transcribe data is required) We regret that we are unable to perform personal research for anyone. All data we come across will be added to this site. We thank you for visiting and hope you'll come back again to view the updates we make to this site.
