History and Genealogy


Genealogy Trails.... "Always Free, Always Updating."



This County is available for adoption!


Our goal is helping you find your ancestors by placing data online for the FREE use of all researchers.

As data becomes available, we put it online on its corresponding county's page.  Information will be posted as fast as we can find, type and/or receive it. 

If you have a love of history and genealogy, enjoy helping people, and have a basic knowledge of web authoring, consider joining us!  Visit our Volunteer Information

If Hosting isn't for you, you can still support our efforts.

We need data - chances are, you have obituaries; birth, marriage and death records; biographies, etc. - RAW data you used to create your family tree.  Please consider contributing those materials.  Anything contributed will remain YOUR property, will be credited to you, and will be promptly removed, should you ever request it.

We need help transcribing as well. Email Me if you have contributions, or can help transcribe materials.
