MARK WORKMAN.
Mark Workman, deceased, was a native son of the Buckeye state. For many years he made his home on the farm which his widow still owns, and was successfully engaged in agricultural pursuits, being an industrious, enterprising and energetic man, of good business and executive ability. His birth occurred in Brown township, Knox county, on the 19th of April, 1852, and he was early injured to the labors of field and meadow, while the educational advantages which he received in his youth were those afforded by the common schools of his locality. After putting aside his text-books as a scholar he again entered the school room as. an instructor, and for a considerable period instructed the young along lines of mental advancement. On the 27th of December, 1876. he was united in marriage to Miss Angeline Hays, and their union was brightened and blessed by the presence of one daughter, Estella, who became the wife oT V. L. Horn, a prominent and successful agriculturist of Pleasant township, Knox county.
Soon after their marriage the young couple removed to the farm in Pleasant "township which Mrs. Workman still owns, and here our subject was extensively engaged in agricultural pursuits until his life's labors were ended in death, passing away on the nth of April, 1885, in the faith of the Brethren or German Baptist church, of which he was a worthy and acceptable member, ever doing his full share to promote the cause of Christianity. His life was one of marked industry and enterprise, in which a resolute spirit and untiring labor enabled him to advance steadily step by step until he occupied an enviable position on the plane of affluence.
Mrs. Workman resided upon the farm in Pleasant township until 1889, when she removed to Gambier and erected the beautiful residence which she now occupies, but she still retains possession of the homestead farm, which consists of two hundred and ninety-seven acres of rich and fertile land. She still holds faith in the same religious society, and her life has been one in which many acts of kindness have gained for her the esteem and friendship of all who know her.
