David H. Coulson, son of John D. Coulson, was born in Chariton County, Missouri, near the town of Keytesville, November 16, 1830. He remained in the place of his birth until he was about seven years of age when his father moved to Howard County, Missouri, where the family remained about two years. In 1839 the family came to Daviess County and settled in Union township. David remained at home until he was about twenty-one years of age.
Mr. Coulson was engaged in farming in Union township, Daviess County, Missouri, for three years. He then moved to Liberty Township, where he remained one year. Removing a short distance from this place, he gave his attention for about eleven years to farming and stock-raising. Moving then to Sheridan township he purchased land in section thirty-five where he is now living.
In 1860 Mr. Coulson went to Nevada City where he was engaged in mining about eighteen months. He returned home in 1862 when he was enrolled in the Home Guard Militia, and served at intervals during the war.
Mr. Coulson was married, in 1852, to Miss Elizabeth J. McBrayer. They have had six children: Samuel D., Sarah M., Thomas R., May C., William B. and Charles H.
