Dear Mr. Chaplin,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Indexes to the Carded Records of Soldiers Who Served in Volunteer Organizations During the War of 1812 in the Records of the Adjutant General's Office (Record Group 94) that includes index cards for Kingsley, Ebenezer C - State: New York - Regiment: Cavalry (Willcocks'), New York and Kingsley, Ebenezer C - State: New York - Regiment: 1 (Davis'), New York Militia which may be a match for Ebenezer Chaplin Kingsley. It is not clear from the cards if they are two distinct soldiers or one person serving in two different units over the course of the war. These cards indicate that there should be corresponding compiled military service records in the record series titled Carded Records Showing Military Service of Soldiers Who Fought in Volunteer Organizations During the War of 1812 in Record Group 94. While some of these compiled military service records have been digitized and can be viewed online through the Catalog, the files for Ebenezer C. Kingsley are not yet available online. There may also be a pension file for him, which is also not available through the Catalog.
To order copies of these records, please fill out a NATF 86 for service records and a NATF 85 for pension records and mail them to the addresses listed on the forms. You can also place your order online using eservices.archives.gov. For more information, please see Requesting Copies of Older (pre-WWI) Military Service Records.
Please note that the National Archives and Records Administration has suspended reproduction and digitization services until further notice due to COVID-19. Orders will not be serviced until operations can resume safely. We apologize for any inconvenience. Once operations resume, document reproduction requests will be filled in the order in which they were received.
Also, because he served in a New York militia unit, there may be additional records concerning his service at the New York State Archives.
We hope this information is helpful. Best of luck with your research!
