Willink was originally formed in Genesee County, from the Town of Batavia in 1804, before becoming part of Niagara County in 1808. When Erie County was formed from the south part of Niagara County, Willink became the south part of that new county. Willink already had been divided to form the Town of Clarence in 1808, which formed the northern part of the yet unformed Erie County.
As new towns were constructed in southern Erie County, none ultimately chose to retain the name "Willink," so that the town was sub-divided out of existence.
The village of Willink continued, but eventually was renamed East Aurora. Though Willink ceased to be an incorporated village in 1874, a post office remained at the west end of the new village of East Aurora until 1913, when it was consolidated with the East Aurora Post Office.
