Instanter is an inhabited place.
This community is now known as Clermont and is in McKean County, PA. It was established as Instanter in 1809, but was mostly abandoned & dismantled during the War of 1812. Efforts were made a handful of years later to reestablish the community as Clermontville, then Clermont, slightly adjacent to its former location.
