Old Jefferson Town

Oskaloosa, Kansas

where an ongoing record of the past is preserved and recorded for future generations

Jefferson County Historical and Genealogy Society


The Jefferson County Historical Society (JCHS) and Jefferson County Genealogy Society (JCGS) have worked hand in hand for the past 50 years preserving and recording the history of Jefferson County Kansas.  The two societies share the responsibilities in maintaining Old Jefferson Town. 


Old Jefferson Town consists of 10 buildings and a prairie grassland that preserve and exhibit donated artifacts (objects, documents, photos, books, maps, etc.)  It has an extensive genealogy library open to the community on weekends throughout the year and by appointment. 

A variety of volunteers keep the museum up and running. Recently the Genealogy and Historical society merged to better meet the needs of Old Jefferson Town.  JCHGS meets monthly to  hold a business meeting to discuss events and the needs of the facilities.   Community members are encouraged to be a part of the meetings. 


Volunteers work on accessioning and displaying objects, clipping and filing paperwork (obituaries, maps, family histories, photos etc.), planning events and connecting to the community through the local newspapers and social media.  Local school groups and 4H groups help with projects outside keeping the grounds picked up and landscaping maintained. 


The City of Ozawkie has a timeline of  historical information about the history of Ozawkie. 

A brief time line borrowed from their webpage: 

1819 – U.S. Government Exploring Expedition under Major Long was said to be first white men to have visited the area.

1825 – After the Indian Treaty of June, 3 1825, Major Daniel Morgan Boone, son and 7th of 10 children of famed “Kentucky Pioneer” Daniel Boone, arrived to this area after being appointed “Kansa Indian Agent” where he was to advise the area Indians on agriculture matters.

1828 – On August 22nd the first white child born in Kansas Territory, Napoleon Boone, was the 12 child of Maj. Daniel Morgan Boone.

1831 – Delaware Indians, originally from the Lenape People from the Delaware Region, complete their move to Kansas from Missouri.

1854 – Kansas becomes a Territory. The Delaware Nation lands were surveyed and each tribe member received compensation for all but a small portion of their land by the United States, which was dispersed in the “Delaware Trust Land” sale. Both Pro-Slavery and Free-State Settlers came to Kansas to set claim on land. The first election was held in the district and a rivalry broke out between the two groups.

1855 – Osawkee boundaries were surveyed and town becomes county seat, the first post office, and first school house were also built. A bill was introduced in Legislature to change the town’s name to Wabash, which failed to pass.

1856 – Under the order of Colonel Whipple, many pro-slavery homes of Osawkee were raided with the aid of Captain Ephrain Bainter, a free-state man who was later elected free-state sheriff of Jefferson County.

1857 – Federal Lands sales take place and the area population rises to 3,500 due to an influx of immigrants. Unmarried men were said to be obliged to pay 25¢ per acre more than a married man.

1858 – An election was held after the Legislature of 1857-58, which gave the people of Jefferson County the ability to vote for the county seat. With 177 votes, Oskaloosa became the new county seat of Jefferson County. In the middle of the night a short time after the election, the court records were seized and transported to Oskaloosa via an oxen drawn wagon.

1860 – The remaining “Delaware Trust Land” was given to the Leavenworth and Pawnee Railroad to make way for the railroad, of which had never been built. A great drought plagued the area.

1865 – A water powered flour and grist mill was constructed by William Dail and J. M. Funk just south of Osawkee. It was used by the government to grind grain where they supplied flour to the remaining Delaware Indians occupying a small area of land south of Osawkee.

1867 – Due to their tiring of the “white man’s antics”, the remaining Delaware Indians moved out of the Osawkee area where they eventually settled in Oklahoma. 1870 – Drought and depression hit hard for the area forcing some to move; decreasing the population to 1,600.

1872 – Flooding of Osawkee.

1874 – Massive invasion of the grasshopper wiped out entire crops and anything else in their way.

1875 – Due to the frequent invasions by grasshopper, the town’s folk changed the river’s name from Grasshopper to Delaware.

Kansas Digital Access to History Grant awarded to Jefferson County Historical Society

The Jefferson County Historical and Genealogy Society has been awarded a $3000 grant  from the Kansas State Historical Records Advisory Board (KSHRAB) to work towards bringing the Old Jefferson Town historical archives to a digitized format. If all goes well, the digitized format will be available online around the first of June to not only Jefferson County, but others across the United States and World. 


The Kansas State Historical Records Advisory Board (KSHRAB) seeks to encourage Kansas organizations and individuals to preserve  records of the past by offering a digital grant to aid in the process of digitizing records into a shareable format to the public. Their funds are granted from the National Historical Publications and Records Commission (NHPRC). 

Volunteers from the OJT museum began working January 10th to enter the thousands of objects, photos, archives and library items into a software program purchased with the grant money.  The Past Perfect Software offers organization of the records that have been kept on paper for the past 50 years.   The digitizing of the museum artifacts will make researching easier, not only at the museum, but also from the comforts of your home.  The Past Perfect system will allow us to locate the items in the museum quicker if you want to come and see an item in person. 


Currently, there are eleven volunteers who are working consistently each week at getting data entered into Past Perfect.  So far over 5000 objects, photos, books, paper documents, etc have been entered into the system. We have inserted over 1500 Jefferson County names into the system that are linked to biographical information, objects, photos, books, maps and any documents that have been donated to the museum by that person or their family.    


While the project is progressing much more quickly than  ever imagined, please understand that this project is a 3-5 year project.  When working with each record entered, each item can take anywhere from 4-10 minutes to enter.  That’s a lot of volunteer hours. Just to give you an idea of what we have to work on...there are over 30,000 photos in our file cabinet that need to be scanned and data documented. In the museum buildings alone, I’m guessing that there are at least 5,000 - 10,000 objects that will need to be photographed and data entered. Our genealogy library is growing each day, there are over 5000 books in the library.  There are thousands of family files and obituaries that someday could be scanned and connected to families and names in our system. 


There are some ways that you can become involved in this project.  If you have an hour or two a week or every couple of weeks, we can keep you busy.   We are in need of volunteers who can scan photos and documents, file clippings, and assist with the cataloging of the numerous library books and photos that we house in our genealogy library.  No experience is necessary, we will train you. 


Volunteer hours are: Tuesday’s 11:00 am to 4:00 pm and Saturday’s  1:00 pm - 4:00 pm.

Public Access to our museum records!

We are a work in progress!

This is just a beginning!  

Our volunteers have been working diligently since January to provide you with access to Old Jefferson Town artifacts.  You will want to check in with us frequently as we add more to our public access catalog.  

Each item that we enter and item, it takes 4-10 minutes to enter.  We have entered over 6,000 items, thus far.  That's a ton of volunteer hours.  We wouldn't be this far along, if it wasn't for them!

As you browse, if you see something that you can give us more information about, please use the feedback link at the top of the page.  We'd love to hear from you.  If you see typing errors, please help us by letting us know.  You won't hurt our feelings!
