CHARLES B. BOYACK
Charles E. Boyack is now living practically retired in Independence, in which city he took up his abode in 1908. Indolence and idleness, however, are utterly foreign to his nature and to some extent he continues active in the field of surveying and engineering work. He was born in this county in 1862, a son of William and Jane (Doig) Boyack, both of whom were natives of Dundee, Scotland, born in 1822 and 1824 respectively. They were reared and married in that country and there the father learned and followed the trade of linen weaving. On crossing the Atlantic to America they took up their abode in Rockford, Illinois, in 1851, and there spent two years, during which period he was foreman of a lumber yard. In 1853 they arrived in Buchanan county, settling in Sumner township, where Mr. Boyack purchased land and began farming. In addition to tilling the soil he engaged in raising thoroughbred shorthorn cattle and Poland China hogs and took several prizes at the county fairs. He was, however, not much of an exhibitor, being more of a breeder. He had no political aspiration for himself, yet was active in politics in Sumner township and labored earnestly to uphold those principles in which he believed. Many sterling traits of character won for him the confidence and high regard of those with whom he came in contact, and he remained one of the valued residents of Buchanan county until his death, which occurred in 1901.
Charles E. Boyack, who was the youngest in a family of six children, acquired his early education in the common schools of Buchanan county. When about twenty-five years of age he formed a partnership with his father to carry on general farming and stock-raising, making a specialty of pure blooded cattle and hogs. Year after year he continued to live upon the farm until he removed to Independence. At different times he has been called to public office. In 1894 he was elected county supervisor on the republican ticket, and he has also been county surveyor for six years and county engineer for three years. He had acquired his knowledge of engineering when working in that way as a boy upon the farm and he still engages in engineering to some extent. He yet owns farm lands in Buchanan county, but is not actively engaged in their cultivation at the present time.
In August, 1892, Mr. Boyack was united in marriage to Miss Helena Clue, who was born in Buchanan county and in early life was left an orphan. Her father came to Iowa direct from Germany. He was a stonecutter by trade and worked in connection with dressing the stone used in the building of the state hospital but lived upon a farm. He had only two children, Mrs. Boyack being the younger. By her marriage she has become the mother of two daughters.
