After marriage Jeremiah and Selinda settled on the homestead, where he was engaged in farming until his death. The sawmill owned by Jeremiah was the pioneer manufacturing industry in Greenwich Township, and he operated it in connection with the farm until about 1840 when he sold it.
In 1856 he left the Whig party, and became a Republican, and he served as clerk of Greenwich Township for years.
In religious connection he and his wife were members of the Universalist Church. ~The Firelands Pioneer I, 1899
