What records are available in Butler County, PA?

Birth and Death Records were mandated by the Commonwealth of PA from 1852 to 1854, but due to lack of participation, the practice was stopped. In 1893 the Commonwealth again mandated that all residents report births and deaths at their County Courthouse. This practice lasted through December 31, 1905 and those records are maintained in each county. Beginning January 1, 1906, birth and death records are recorded at the State level. More of these records are available online for state residents as each year passes. To request a certificate for records created in 1906 or after, visit to print out the appropriate order form for all states in the United States.  Birth records and Death index for Butler County are available at

Marriage Records were mandated by the Commonwealth of PA from 1852 to 1854, but due to lack of participation, the practice was stopped.

The index for Butler County Estate records is available online.

This estate index of Butler County, covering the years of 1800-1910, has been compiled from the estate index at the Butler County Courthouse.  No claim is made to this index being a complete compilation of all estates in Butler County during those years, but it should have most of them that are available.  This work has not been proofread.  It is being posted here merely as an aid to give one direction in the search for their ancestors. Because some letters of the alphabet do not have as many entries as others, you will find this estate index goes beyond 1910 in some cases.

If there is a will it will be included in the estate papers.  But there can still be estate papers for people who left no will.  Estate papers include appraisals of goods, personal property, and real estate owned by the deceased.  A disbursement page is normally included in the estate and may name the heirs.

The complete records are now online at www.familysearch.orgChoose  United States  under the Browse by Location section.  Then scroll down and choose Pennsylvania.  When that page opens, click on Browse through 3,197,552 images.  That will open a page that allows you to choose Butler County.   You will see the Butler County Orphans Court and Probate records files.  The index posted here should help guide you in finding the estate file you are looking for.
