Finding Ancestors wherever their trails led
Genealogy and History

 

Welcome to the Genealogy Trails website
for Jefferson County, New York


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.

This site is available for adoption!

If you have a love for history, a desire to help others, and basic webpage-making skills, consider joining us!
Get the details on our Volunteer Page.
[A desire to transcribe data and knowledge of how to make a basic webpage is required.]

If hosting isn't for you, we can use your help in other ways.
More information can be found on the Volunteer Page.

Until we get a dedicated volunteer to maintain this site, we'll do the best we can to add data as we come across it. You can send your family's raw data (transcribed birth/marriage/death, cemetery, census, biography records) to us and we'll include it on this site.

WE REGRET THAT WE ARE UNABLE TO DO PERSONAL RESEARCH FOR YOU.
