I didn't find her on the Census records 1850-1870.
in New York, births, deaths and marriages were recorded and filed in the Town Clerk's offices. I'd contact the Lee Town Clerk, https://townlee.digitaltowpath.org:10076/content/Offices
about her marriage license.
I'd contact the Rome Historical Society, www.romehistoricalsociety.org/
and the Jervis Public Library, www.jervislibrary.org/genealogy.html
and ask if they have any info about her. Successful Searching!
