Colorado 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.

This county is available for adoption!

If you are interested in joining Genealogy Trails as the host of any of our
county websites, view our Volunteer Page for all the ins and outs of becoming a host.

(Enough knowlege to make a basic webpage and a desire to transcribe data is required.)

County Information
Summit County was organized as one of the seventeen original Colorado counties by the First Territorial Legislature on November 1, 1861. It was named forthe many mountain summits in the county. Until February 2, 1874, its boundaries included the area now comprising Summit County, Grand County, Routt County, Moffat County, Garfield County, Eagle County, and Rio Blanco County. In 1874, the northern half of the original Summit County was split off to form Grand County, with the creation of Garfield and Eagle counties in 1883, Summit County arrived at its present boundaries.
