Jonathan III moved from Philadelphia to a place in Maryland, only a few miles from Emmitsburg, along a small river known as the Monocacy. There he decided to settle, having been told that the Indians in that part of Maryland were very friendly. Members of the family have tried, without success, to locate exactly where Jonathan III settled. The best we have been able to establish is that his land bordered on Tom's Creek, about a quarter of a mile above the point where the Creek enters the Monocacy river. [Editors note: In 1996, the Emmitsburg Historical Society located pinpointed the exact location of the Hays Family Homestead along Tom's Creek] There he married Mary Henderson, born June 17, 1732, who is supposed to have come, from Nova Scotia. From their marriage came five children, Jahue, John, Joseph and two daughters. Little is known about Jahue and John and the daughters, but it is the son. Joseph, born in 1760, whose life is fairly well documented.
