Many of Burton's original settlers came from the towns of Adams and Henderson in Jefferson County, New York. For twenty years the area was known as the Atherton settlement, after the brothers Shubael and Perus Atherton and their nephew Pliny Atherton Skinner, later joined by another brother, Adonijah, who settled on Thread Creek in 1835.
More about Burton
The area was first part of Flint Township, and from 1839 to 1843 its northern part belonged to Kearsley Township before returning to Flint Township. When the City of Flint incorporated, the Genesee County Board of Supervisors separated Burton Township from Flint Township on October 12, 1855, though the first township meeting was not held until April 7, 1856, sometimes taken as the date of organization. A post office opened on December 13, 1861, with Horace L. Donelson as postmaster, but operated only until August 6 of the next year. Over the years Flint annexed large parts of the township's northern and western sides. On May 16, 1972, township residents voted to incorporate, and the City of Burton was formed on July 1 of that year.
