In 1803 Slippery Rock Twp. was much bigger than the current Slippery Rock Twp. It included the portion of the county north of an east-west line drawn from the northern corner of the western boundary of the County. In regards to the current townships, this area includes all of Slippery Rock, Allegheny, Cherry, Marion, Mercer, Parker, Venango, and Washington Townships, portions of Brady, Clay, Concord, Fairview and Worth Townships, the Boroughs of Bruin, Cherry Valley, Eau Claire, Fairview, Harrisville, Petrolia, Slippery Rock, and West Sunbury, and parts of the Boroughs of Karns City and West Liberty.
This information is from pages 59 through 63 of the 1895 Butler County History. This source also includes the number of cows/oxen/horses owned, the valuation, and the amount of the tax, but since this information seemed of limited usefulness to genealogists, it has not been transcribed.

Note:
The 1895 History alphabetized 'Van Huston' under 'V', but it seems likely
that Van may be a given name.
