John Ingersoll was born in North Castle, New York in 1817. The family moved to New York City, where in 1828 John's parents died. He was adopted by his uncle, and two years later began an apprenticeship as a printer at a newspaper in New York. In 1837, Henry Barnes, owner of the Detroit Free Press, noticed Ingersoll and invited him to work in Detroit. Ingersoll moved there with his wife Harriett, but the next year he left the Free Press to become foreman on the Detroit Daily Advertiser, and in 1839 he went into the publishing business himself by publishing the Macomb Statesman in Mt. Clemens, Michigan. He moved on the St. Clair, Michigan to publish the Banner in 1842.[2]
Ingersoll continued to wander to different papers, publishing the Lake Superior News and Miners Journal from first Copper Harbor, Michigan and then Sault Ste. Marie, Michigan. He returned to Detroit, publishing two papers there, moved to Rochester, New York, and in 1858 moved to Owosso, Michigan to publish the American. Harriett Ingersoll died in 1860, and John Ingersoll settled down somewhat, entering local politics, and in 1862 merging the Owosso American with the Corunna Democrat, changing the name of the merged publication to the Shiawassee American. He married Mrs. Julia H. Barnum of Owosso in 1864, and built a new house for the family in Corunna in 1868. He continued in politice, and published papers in Corunna and Owosso until his death in 1881.[2]
