To potentially access any surviving records, you would need to try the following:
* New York State Archives: Since the school was located in New York, the state archives might have some records related to its operation, particularly if it was a registered institution. Contact them directly to inquire about their holdings.
* Local Historical Societies (Esopus, New York area): The town or county where the school was located might have a historical society that has preserved some documents or information relating to Wiltwyck.
* University Archives (if relevant): If the school had any academic affiliations or partnerships with universities, those universities' archives might hold some records.
* Private Collections: It's possible that former staff, students, or their families possess personal records or photographs related to the school. Online genealogy forums or historical societies might be able to connect you with such individuals.
Finding records from a closed institution like Wiltwyck will require significant research and patience. Be prepared to spend time contacting multiple organizations and individuals. Be clear about what type of records you are looking for (e.g., academic transcripts, disciplinary records, etc.) to improve your search.
