p.813: A. Shunk Sr.., Bucyrus, whose portrait appears in this work, is the son of Simon and Susan (Harmon) Shunk, and was born March 23, 1797, in Sommerset Co., Pa. He was raised on a farm, and was denied the advantages of schooling, living at home until he was 21. He then made himself tools and commenced working at the carpenter's bench, and for 21 years followed this occupation in his native state. He seemed especially gifted in this line, for, when only 8 years old, he made a minature wagon, perfect in every particular. He never served an apprenticeship a fact which shows his natural skill in the direction of mechanics. In 1843, he bought a patent right for the manufacture of a ber-shear plow, in Green Co., Ohio, and, in the following spring, commenced the manufacture of plows at Xenia, Ohio. He also kept a grocery and tannery for 3 years. He next worked at Canal Fulton, Stark Co., Ohio for about a year and a half. In October, 1854, he came to Bucyrus and started a plow factory. He had about $1,000 capital, and built a brick shop the 2nd. year of his residence, and then he had a surplus of $500. He is now sole owner of the entire block, which has all been made by his own efforts. They turn out about 1,400 plows per year, of 6 different kinds, and which have quite an extended reputation, there being over 100 local agencies in 4 different states. Since he made his 1st. plow, he has made all his own patterns, and has, during the last year, invented a pattern which excels them all. We doubt if there are many men, so advanced in years as Mr. Shunk, who display so much business activity. He is a member of the English Lutheran Church, and has been since his 17th year. His father was in the war of the Revolution, serving under the great Washington. He was married, Feb.1,1816 to miss Mary Banfort, of Sommerset Co.,Pa.There are 12 children living. Of this first marriage there are Delilah, wife of Mr. Stevenson, of upper Sandusky, Allen, mechinist at Fort Wayne; Lavinia, wife of Joseph Miller of Springfield, Ohio; Marian, wife of N.F. Albee, of Kent, Michigan; and Adam. His wife died Aug.21,1844. In 1845, he married Catharine Bauch of Springfield, Ohio. Of this marriage, there are Francis, Nelson, Theadore, Isaac, Thomas W., John L. and Katie.
