From "History of Washington County":

James Dinsmore emigrated to this county from Ireland, and settled first in Fayette township, Allegheny County, Pa., and on the 21st of July, 1795, purchased two hundred and seventy-six acres of land in Canton township, Washington County, of Joshua Anderson, adjoining lands of Francis Cunningham, Samuel Agnew, James Taggert, and William Shearer, it being part of a tract called "Huntington" which was patented to Joshua Anderson, Sept. 26, 1787. On this farm Mr. Dinsmore lived and died at an advanced age. A fort, or block-house, was on the place that later became known as the Dinsmore Fort. He left two sons, John and James and several daughters. The farm was divided between John and James. The former remained on the homestead place till his death, and left four sons - William, James, John C., and Robert. William is still living on the homestead where he was born. James moved to Cross Creek. John C. settled in the township. Robert moved to Buffalo township where he was murdered.

James Dinsmore, son of James and brother of John, lived on his portion of the farm and died there. He had three daughters, one of whom, Mary, became the wife of Henry Graham, a great-grandson of the Henry Graham who took up the land on which Cross Creek village now stands. They settled in Bloomington, Ill. Two of the daughters, Mrs. Samuel White and Miss Jane Dinsmore, reside on the home place.

The direct ancestor of the Washington county branch was James Dinsmore, who was born at Ballywattick, Ireland, April 24, 1742. He emigrated to America in 1761, and settled in York county, Penn. There he married, had three daughters, and buried his wife. In 1774-75 he removed to Miller's Run, in what is now the edge of Allegheny county. There he married again, and had two sons and two daughters. At that time Pittsburgh was but a straggling hamlet, the country was a wilderness, swarming with savage beasts and wild men. That land is still owned by his descendants in the direct line, and it is situated not far from Venice. In 1794 he bought, and in 1796, removed to a large tract of land in what is now Canton township, Washington county, and on that estate the fifth generation of his name and blood are living to-day; this land is situated six miles a little north of west from Washington. This James Dinsmore was a very bulky man, weighing above three hundred pounds; he died in 1817. He was eminent for saintliness, and was an elder in the Presbyterian Church for a great many years. He had two sons, John and James, between whom his landed estate was divided.
