Volunteers Dedicated to Free Genealogy

This website is part of the Genealogy Trails family and 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 county site needs a dedicated host to make this site the best that it can be!
If you think that you may be interested in volunteering to host this site, or any of the other sites we have available, please view our Volunteer Information Page.
(A desire to transcribe data and the know-how to make a basic webpage is required)

Feel free to email us with any and all contributions that you may have - every little bit helps someone!

I regret that I am unable to do personal research.

Ada County was created by the Idaho Territorial Legislature on December 22, 1864. It is named for Ada Riggs, the first pioneer child born in the area and the daughter of H.C. Riggs, a co-founder of Boise. Boise became the capital of Idaho in 1865. Canyon County was partitioned from western Ada County in the early 1890s.

Submit Cemetery Information
A wonderful source of genealogical information that is very useful are cemetery headstones. They provide key data such as dates of birth, marriage information and dates of death. To submit headstone information please click here.

Submit Obituary Information
Obituaries are one of the most important tools used by researchers in tracing their family roots. Please consider contributing any obituary information that you may have by submitting them here and filling out the transmittal form.
Please include your email address should we have any questions.

As your Idaho State Coordinator, I try to post as much source data online as possible in order to make it freely available to all researchers. We gratefully accept contributions of raw data such as  marriage/birth/death records, obituaries, county histories, biographies, old newspaper items, census information, - anything that would help someone build their family tree! Feel free to email me, Sandra Davis, with your contributions - every little bit helps someone!
