Born 1824
From The history of Clinton County, Ohio (1882)
I. M. JOHNSON, farmer, P. 0. Port William. He is a son of John H. Johnson, whose birth occurred in New Jersey five days prior to the celebration of our nation’s freedom. He grew to majority in his native State. About the year 1800, he with his parents settled in the present limits of Cincinnati, Ohio. On June 7, 1810, he married Christina Curie, who is supposed to have been a native of Virginia, born October 18, 1791. They settled in Union Township, Clinton County, Ohio, in the year 1812, and ever after remained a resident of the county, but, about 1830, purchased the farm now owned by our subject. John H. was one of the early pioneers of Clinton County and endured the hardships as such; he was a patriot in the Indian war of 1812. He was a man of strong and portly frame, robust constitution, and able to bear all the duties that devolved upon him. The marks of those pioneers’ hand and ax should to-day be regarded as monuments to their lives. His death occurred August 7, 1853, and his wife, too, followed December 22, 1856. Thus ended the earthly career of two noble pioneers of Clinton, the mother county of Isaiah, one of eleven children, of whom five are now living, and who was born February 28, 1824, in Union Township. He was raised on his father’s farm, but subsequently learned carpentering, to which his time has since been largely given, though living almost entirely on a farm. In early life, his school privileges were very much limited. In the year 1857, he married Miss Deborah Ferguson, who was born in Greene County, Ohio, in 1838. They are the parents of six children. The political affiliations of Mr. Johnson have ever been with the Whig and Republican parties, which have intrusted to his honor the office of Township Trustee several terms, which duties he has faithfully and impartially discharged. He is a man of large stature, and has possessed fair health, but time and hard labor have silvered his hair and left their mark upon his frame. His grandfather, Cornelius Johnson, was a patriot in the war which resulted in our free and independent government.
