The online city marriage index shows that she married Mr. Judge in 1946 in Rochester. the actual certificate would be available from the city archives (which you might already have). She appears with the Davidsons in Rochester in the 1930 and 1940 censuses.
But there is this from the state:http://www.health.ny.gov/vital_records/
While adoption and birth records remain confidential and under court seal,[inserted by me = forever] an adoptee who was born and adopted in New York State, the birth parent of that adoptee or the biological sibling of that adoptee can register with the Adoption Information Registry to obtain certain kinds of information.
The Registry helps adoptees obtain available non-identifying information about their birth parents and enables the reunion of registered adoptees with their birth parents and biological siblings. Finally, the Registry provides a place for birth parents to file medical information updates which may be shared with registered adoptees.
Divorce records indexes (but not the divorces themselves) can be searched in person at the county clerk's office. Not online from outside the office.
