That's 60 years or so before official records were kept by towns. Monroe County as not formed until 1821. Church records might go back that far.
There are lists of what churches are available on film from Cornell University at: http://rmc.library.cornell.edu/eguides/lists/churchlist1.htm...
; there is an UNCATALOGUED, NOT ONLINE book of Congregational records for Wheatland back to 1808 at the Local History Division at the Rochester Library.
They have an ask a librarian email set up: https://roccitylibrary.org/ask-a-librarian/
. Or you could try the Wheatland town historian and the historical society out there as well.
