Granger was part of the Morris Tract and called by the natives Sho-ne-ti-yea.
The area was first settled circa 1816. The town of Granger was established in 1838 from the town of Grove, after having been part of many towns incorporated earlier in Livingston County and Allegany County. At the time the town was established it was called "West Grove", but assumed its current name in the next year, 1839.
