Allegany County was formed in 1806 and the first federal census after that date was the first official census of the county in 1810.  At the time of the census of 1810 there were only 5 Towns in the County of Allegany: Angelica, Alfred, Caneadea, Nunda, & Ossian.  As the county developed and population began to grow the Towns began to change in names and boundaries.  Only 3 of the original Town Names have survived as part of Allegany County, but, the other two Town Names are part of other counties.  NUNDA was formed in 1808 by act of the NYS Legislature.  NUNDA was annexed into Livingston County in 1846.
For further history information about Nunda, you might try the website:   OSSIAN was originally formed as taken from Town of Angelica in 1808.  OSSIAN was annexed into Livingston County in 1857.  For further history information about Ossian, you might try the website:
