Well, that makes perfect sense, with John's middle name being "Young", and John naming a daughter Sarah. I located John "Urguhart" in the 1881 Dumfries Parish, York Co., New Brunswick, Canada census. John, 38, farmer; wife Amanda, 30; Lillian, 5; Sarah, 2; and Lizzie, 8/12 born August 1880. All were born in New brunswick and are baptist. Nathaniel is living nearby in Douglas Parish with his daughter(?) Sarah in the Yerra (should be Yerxa) household (in-laws?). Nathaniel Jr.(?) is living in Douglas with another Yerra household. Nathaniel's wife Sarah is buried in Keswick Rural Cemetery with James W. Urquhart 1843-1920 and Esther Urquhart Yerxa 1862-1925. Did not find where Nathaniel is buried.
