John C. Mowry was born on December 30, 1806 to parents Peter Mowry and Elizabeth Gray in Pennsylvania. John married Margaret Mowry on May 4th or 11th of 1830. The wedding ceremony was performed by Rev. Dr. Black in Allegheny County, PA. (Margaret was his first cousin.)
In 1833, at the time of his father's death, John inherited five acres next to the town of Canton, Ohio, plus one of his two new houses in Diamond Alley, and $1000 in stock of the Bank of Pittsburgh.
After the death of his first wife in 1847, John later married Sydney Jane Gregg on November 20, 1849.
