Grant County was formed in 1831 by settlers from Kentucky and Virginia. It was named for Captains Samuel and Moses Grant of Kentucky, who were killed fighting indigenous warriors north of the Ohio River.[3] Their home county was also named for them, Grant County, Kentucky.

In 1831, Martin Boots and David Branson each donated 30 acres of land to begin a settlement called Marion. This land was on the north side of a fast-flowing and scenic river which the Miami Indians called Mississinewa. Marion was designated as the County Seat.[4]
