Back in the 1800s wandering livestock was a problem that was caused primarily from the lack of fencing. This was such a problem that rules and regulations were made to deal with the stray livestock. In Ohio the first act regulating estrays was created 7 February 1804. 
What is an estray? The definition, according to Black’s Law Dictionary, Estray: Cattle whose owner is unknown…a wandering beast whose owner is unknown to the person who takes it up…an animal that has escaped from its owner, and wanders or strays about… 
The Estray Book detailed the wandering livestock’s markings, who found it, when it was found, who claimed it and when it was claimed, if it was ever claimed. Soon after an estray was found a notice of the animal was to be published in the newspaper or printed on a poster by the finder. The animal was appraised. If the owner claimed the animal within a year he was to pay the taker-up payment for feeding, boarding and advertising. If the owner did not come forward the animal became the property of the taker-up or was sold. The Estray book was kept by the local Justice of the Peace and a copy was given to the Town Clerk. These books were often kept at the county courthouse.
I have heard about these early county books but had never actually seen one. Thanks to Catherine (Leininger) Miller’s son Jerry who gave me the old Estray Book of Liberty Township, Mercer County, Ohio. This old book, dating back to 1842, was stored in Catherine’s attic with some other old books. The Estray book was probably passed down to her father, Ted Leininger, who was once a Liberty Township Trustee. Jerry knows I have an interest in the history of the Chattanooga area and graciously thought of me when he found the books. I plan to scan and digitize them and transcribe and index them before I pass them on to another entity for safekeeping.
The Liberty Township Estray Book contains dates from 1842-1880. The little book is about 6 ½ by 7 ½ inches with pages that are not numbered. I began transcribing the book as it was written, misspellings, capitalization and all. There are about 58 pages in the book with writing on both sides of the pages. I have just a few pages transcribed so far and below are some examples from the book:
