I live in Jefferson County, Pennsylvania and have done a ton of research in Clarion County. There was no David Kirkpatrick living in Clarion County. There was a David Shields Kirkpatrick that lived in Armstrong County (Dayton, PA to be exact). His father's name was James Kirkpatrick and was a Revolutionary War Soldier. He and his wife came to Armstrong County from Westmoreland County. There is information on James at the Westmoreland County Website of RootWeb.
