Genealogy and History

Welcome! and Happy Trails to you on your quest for your ancestors

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.

Regularly adding fresh, interesting and NEW data to this site leaves me no time to do personal research, but we can help answer questions and accept your data contributions; feel free to email me, Julie Schadek, your county host.  We Thank you for visiting and hope you'll come back again to view the updates we make to this site.

Elijah L. West brought to the section, and put into active operation, the first combined mowing and reaping machine ever used in Jefferson county. Mr. West is justly recognized as one of the very first settlers in the Wheatridge section, the entire region being an undeveloped wilderness at the time of his location here. Not only has he been a witness to the growth and developments of the community, but has also had active part in bringing about the transition. He was also one of the most active workers in organizing the Wheatridge Grange, of which he became a charter member and was elected the first master, a position he has filled, at various times, to the extent of more than ten years. This was the first Grange to be established in Colorado, receiving Charter No. 1.

In 1873 George W. Harriman was the builder of a large reservoir, the first in Colorado, and he became the father of the great system of storage reservoirs now so prominent a feature in the development of the state and the promotion of its agricultural interests.

This is a farming region, about 6 miles north of Golden City. A neat little frame church was built here under the pastorate of Rev. Jesse Smith, costing about $1800. This is the first strictly rural church ever built in Colorado. The pastors of this circuit have been W.M. Smith, D.W. Scott, Jesse Smith and G.W. Swift, the present pastor.
