The Downriver community of Trenton was founded in 1834. It was then called Truaxton. In 1850, a
new plat was recorded under the
name of Trenton. It was again incorporated
February 10, 1855. In 1929, a portion of Monguagon Township, called Sibley, was annexed to give Trenton it's present size. In 1957, Trenton became a city. Trenton sits to the west of Grosse Ile, to which it is connected by two bridges.
