From 20th century history of Springfield, and Clark County, Ohio, and representative citizens (1908)
AYDON ALLEN, who owns 146 fertile acres of what was formerly known as the old Thorpe farm, in Spring-field Township,, was born in Harmony Township, Clark County. Ohio, September 3, 1846, and is a son of William and Rebecca C. (Henkle) Allen.
William Allen was born in New York and was a son of William Allen, who was born in Yorkshire, England. The first William Allen came to America in young manhood and settled in New York, subsequently removing to Cincinnati, Ohio. When his son William was about ten years of age he came to Harmony Township, Clark County, where he took up a quarter section of land and on that farm he lived during the remainder of his life. AVilliam Allen (2) passed the whole of his life from the age of ten years on the same place. He married Rebecca C. Henkle, who was a daughter of Joel Henkle, and the granddaughter of a noted German scholar, who had seven sons, five of whom became Methodist ministers. Joel Henkle's inclinations turned toward agriculture instead of the ministry and when he reached manhood he came to Clark County and settled in Moorefield Township, where Mrs. Allen was born. William Allen (2) remained with his widowed mother until lier death, when he inherited the old Allen homestead of forty-two acres. He had three children: Aydou; Joseph W., who was formerly county recorder, residing at Springfield; and one died in infancy.
Aydon Allen was reared on the old Allen farm on which he lived for fifty years and six months. He obtained his education in the country schools and in young manhood worked as a farmer. When twenty-sis years of age he began to teach and for sixteen years followed the profession through Harmony and Moorefield Townships. After he retired from the educational field he returned to his farm, on which he continued to live until March, 1897, when he moved to his present place. Prior to this, however, he had bought his brother's interest in the old Allen farm, which then contained sixty-five acres, and he disposed of the property in 1901. Here he carries on a general farming line. He is widely known and highly esteemed and if his neighbors have ever found fault it has been because of his never setting up a domestic hearthstone, Mr. Allen never having married. He is identified with the Masons and the Knights of Pythias, and is a member of the M. P. Church at Harmonv.
