HARRISON HEFFNER, farmer, P. O. Herring, was born in Ross County, Ohio, December 25, 1834. Isaac Heffner, the father of our subject, was prominent among the self-made men of this county. Commencing in life a poor man, with but a limited education, he eventually became one of the largest land owners of the county, and at the time of his death owned about 1,500 acres of land, nearly all of which he had improved. He was born in Pennsylvania, February 12, 1809, and when a child was taken by his parents to Ross County, Ohio, where he grew to maturity. In May, 1833, he married Mary May, born in 1807, daughter of John and Mary (Strouse) May, natives of Pennsylvania, and early settlers of Ross County. In about 1842 Isaac Heffner came with his family to this county, and here erected the first brick house built in Jackson Township, where he died May 30, 1884. He was a very public-spirited man, and much credit is due him for the present state of development Jackson Township has obtained. He was the founder of the church deeded to the Christian denomination, although for years a member of the German Reformed Church. Our subject has resided upon his present farm since 1863. He is one of the most extensive stock dealers in this vicinity, his herd consisting of thoroughbred shorthorns. He was married April 30, 1863, to Miss Mahaley Ice, who was born, in Auglaize Township, this county, March 11, 1842, daughter of Samuel-and Mary (Shelenberger) Ice, natives of Pennsylvania, and who are among the early settlers of Auglaize Township, this county. To this union were born six children: Mary L., Charles E., Jennie A., Rison B., William G. and Harry H. Mr. Heffner has served the people of Jackson Township as trustee. He has for several years been identified with the Gennan Reformed Church. In politics he is an active Democrat.
