The father of your Jacob Dishong is Henry Dishong who was born in Ohio in 1834. He and his wife Sarah (possibly Sarah Stout) had Jacob, 1860, James 1863, Rosa Bell 1869, Laura 1873, Wesley 1876 and Almond 1880. The 1900 census for South Whitley, Indiana gives the birthplace of both his parents as Pennsylvania. The 1860 census from Warren, Huntington County, Indiana shows Henry and Sarah have a son Jacob who was then 4 months old.
