Your local genealogy and Research Library

Find your family genealogy in our family history files and Research Library

There’s more to genealogy than creating a family tree

Genealogy research can reveal a lot about your past to help you understand the future. Not only can you find photos, letters, contracts, and family Bibles, you can potentially discover patterns in causes of death, marriage, births, and service in the armed forces.

Find answers to your family’s biggest questions and uncover long-lost details

Hundreds of families and surnames are on file in our Research Library. Find photos, newspaper clippings, land records, and family history books.

Your next research breakthrough on local ancestors might be waiting.

“Where did my family come from?”
“Where did my grandparents get married?”
“Do I have any famous people in my family tree?”

  • The Warren County Historical Society can help you answer these questions and many more about your family history.
  • Research materials in the WCHS Research Room at the Museum are available for study by the public.
  • There is no charge for private personal study or research.
  • The only charges are for a volunteer researcher’s time as needed and/or photocopies of records.

Let us do some of your genealogy research for you

Our research volunteers and librarians can do some of the research for you. This is especially helpful for people unable to visit the library directly. Just make a research request. 

  • When requests are received, either via this site, email, postal mail, or telephone, the request is entered into a queue.
  • The research is then conducted in chronological order by date of the request for $25 per hour.
  • Typically, research is finished in about 30 to 45 days after you request it.
  • Volunteers conduct the research and their availability varies. Your donations can help support them and the Museum.

All research is conducted by talented volunteers in the order it is received. You’ll receive an estimate of cost and timing before work begins.

Other records and reports

Warren County Probate Records

When an individual dies, a court procedure to determine what happens to the deceased’s estate or to divide assets based on a will begins. This is called Probate.

These records are extremely helpful in determining “what happened next” after someone dies. We have Probate Records from 1833-1900.
