Bloomfield, now Trenton, was platted Feb. 27, 1816, by Michael Pearce and Stephen Gard. It honored Joseph Bloomfield (1753-1823), a veteran of the American Revolution, governor of New Jersey (1801-1812) and later an officer in the War of 1812 and a U. S. congressman (1817-1821). There is a Bloomfield, named for the same person, in Essex County in New Jersey. The name of the Butler County town was changed to Trenton when the first post office opened March 6, 1821, because there was another Bloomfield in Ohio (Trumbull County). There are now five Bloomfields in Ohio:
(1) in Bloomfield Township in Trumbull County, north of Warren;
(2) in South Bloomfield Township in Morrow County, northeast of Columbus;
(3) in Coshocton County, north of Coshocton;
(4) in Muskingum County, northwest of Cambridge; and
(5) in Washington County, north of Beaverton.
There also is a Bloomfield Station in Jefferson County, west of Steubenville.
