The area covering the City of Milford, O'Bannon Township, and part of the City of Loveland is from a single 1788 survey by John Nancarrow, a Revolutionary War veteran from Virginia. As one of Clermont County's major historians noted, "No wonder, then, that it struck with rapture the quaint and eccentric John Nancarrow, who had it surveyed for him on May 28, 1788 as Dutch burgomaster intended to found a city that should become the future metropolis of the West." Miami Township was created in 1801 as O'Bannon Township, after O'Bannon Creek, a tributary of the Little Miami River that runs through the township. This creek was named for Clermont's first surveyor, John O'Bannon, who was not connected to, responsible for, or interested at all in Nancarrow's survey area. John O'Bannon had instead made the county's first survey on Virginia Military District land on Nov. 13, 1787, on the site of the village of Neville. The township's name, shortly after 1801, was changed to Miami, after the Little Miami River. The particular stretch of the circle highway Interstate 275 was completed in 1975, built through the middle of the community.
