He, too, worked to some extent in the coal mines and was employed in pulling coal out of the pits with engines. In 1862 he went to Utah and settled in Salt Lake City, working in the mountains at chopping logs. He was likewise employed In sawmills and with the building of the railroads into the state he secured employment of that nature.

He ran the first train south of Salt Lake and was employed as an engineer for twenty years. In 1884 he removed to Rigby, Jefferson County, Idaho, where he took up a homestead, and his sons secured also three quarter sections, the four tracts being all in one piece. Mr. Kinghorn improved and cultivated his land, residing thereon until his death. The farm is situated about four miles from Rigby.

They came to America in 1854 and tor a time resided in Missouri and later in Illinois, where they lived for eight years, removing then to Utah. It was in 1862 that Mr. Campbell arrived in Salt Lake City, where he spent his remaining days, his death occurring in 1877. The mother died in 1873. Their daughter, Mrs. Kinghorn was born in Roshaw, Scotland, December 15, 1843. By her marriage she became the mother of thirteen children, all of whom are yet living: George, born December 13, 1860; David, May 6, 1862; James, October 30, 1864; William, February 7, 1867; Alexander, March 22, 1869; John.

The first two were born in Belleville, Illinois, the last two in what is now Jefferson County, Idaho, and the others were all born in Salt Lake.

Mr. Kinghorn made a business of raising stock, especially horses and cattle, and was quite successful in his undertakings, so that at his death, which occurred March 18, 1915, he was able to leave his family in comfortable financial circumstances. His political support was given to the democratic party. His religious faith was that of the Church of Jesus Christ of Latter-day Saints and he served as bishop's counselor for several years and at the time of his death was a patriarch.
