Franklin County is proud to be named for Benjamin Franklin, American founding father, writer, printer, diplomat, activist, and scientist. But, to date, proof of a visit from Mr. Franklin to the county has not been found. Yet, besides the name, there is a connection between Benjamin Franklin and Franklin County. The connection is with Benjamin Chambers, who selected Franklin’s Philadelphia Gazette to advertise sale of lots in the town he was prepared to establish.

Franklin County was the 14th county of Pennsylvania. As the colony of PA grew, the original PA counties of  Bucks, Chester, and Philadelphia Counties were divided into more counties.  Lancaster grew out of Chester, Cumberland grew out of Lancaster, and Franklin grew out of Cumberland. Franklin County came into being on September 9, 1784, and the town laid out on “Conegogig Creek” (Conococheague Creek) was named the county seat in the legislation, forming Franklin County.
