John Clark was a native of Westmorland County, PA, having been born there on April 17, 1825. He came to Jefferson County at the age
of 19, making his home in Brookville and later in Pine Creek Township. After coming to Jefferson County, he met and married Sarah Jones in 1850, and they settled on a farm in Pine Creek Township near the
Butler Cemetery. Sarah was the daughter of Samuel and Eleanor Jones, who were also among the earliest settlers of Jefferson County.
The Clark's were the parents of ten children: Josiah Reynolds, Clarence Samuel, William Gilbert, Charles Ashball, Barnett Jones, Jared Joshua Ellsworth, Lizzie Alice, Raymond Francis, Edgar Mayne
and John Lester. Raymond, Ellsworth and William did not survive their father.
John was well known in the area as "Seneca John", and was a
successful hunter, trapping many fur-bearing animals in the North Fork area, no matter how cold the temperature or how deep the snow. He
was a familiar figure in Pine Creek Township until his death in 1919.
Sarah Jones Clark was born at Handy in 1827, and passed away in
1889, her obituary stating that she died in the same house where she was born. She was the sister of Joshua Jones, also a local resident of Jefferson County. Sarah was buried in the nearby Butler Cemetery. After her death, John and their daughter, Alice, moved to the Jefferson County Home where John died June 20, 1919.
He was buried beside Sarah, who had died twenty-nine years before.
