Henry D. Coulthard, a farmer residing on section 12, Holt township, was born in Jo Daviess county, Illinois, December 6, 1866, and is a son of Henry and Mary (Hutchinson) Coulthard, whose sketch appears elsewhere in this volume.  He is the second in order of birth in a family of ten children.  As he was about five years of age when he came to this county he can remember some of the struggles of the early years, and at an early age he began to assist in the work on the farm.  He received a fair education in the district schools but his practical preparation for life and for the vocation to which he has devoted his energies was obtained under the guidance of his father.  At the age of nineteen he married and set out to make his own way in the world.  He now owns one hundred and sixty acres of land, which he bought from his father under contract.  On this he follows general farming, which has brought him substantial returns for his labor.  His farm is well improved and the fields are cultivated in accordance with modern methods, their appearance demonstrating the skill of their owner.
On the 6th of February, 1885, Mr. Coulthard was united in marriage to Miss Clara Burch, a native of this county and a daughter of John and Brazelda (Greggs) Burch.  Four children have been born to them:  Cecil Francis, George D., John H. and Harold, all of whom are at home.
The family are members of the Christian church and are closely identified with its interests.  When exercising his franchise as a citizen of this republic Mr. Coulthard invariably casts his vote for the candidates of the republican party, as a man who will be guided in his political actions by principles in which he puts the greatest confidence.  He has not held office nor sought for public distinction, although he has served very efficiently as a school director.
