Someone was asking about Monmouth folks who moved on to Washington Co., PA. In the later 1760's a number of New Jersey families settled in the area between the Youghiogheny River and the Monongahela River, often called "the Forks of the Yough," in what is now western Pennsylvania. This area was claimed by both Pennsylvania and Virginia, a dispute that was not finally settled until 1785 by the U.S. Congress.

Records were kept by both colonies and this helps to explain how the Applegate family appeared to be in two states at once. In 1780, Yohogania became part of Washington Co., PA.
