The principal lists of captives taken to Quebec are in the Haldimand Papers in the British Library, in /Add. Mss. #21,843/ (one section of the Haldimand Papers).
They have been extracted quite well by Chris McHenry, who self-published a book, /Rebel Prisoners at Quebec 1778-1783/ (Lawrenceburg, IN: By the author, 1981).
Most commonly seen are transcripts of a list of prisoners releasted, from US National Archives Micropublication #246, roll #135, Item 4, “Prisoners of War,” Document #12, which was transcribed by the War Dept. from a Nov. 1782 list prepared by the Commissary of Prisoners, in the Clinton Papers.This list was oriented to soldiers for the purpose of exchange, so omitted all women and children.It omits many who had been taken to Quebec, and also includes quite a few persons not in the Haldimand Papers lists.
The Quebec lists are not complete lists of captives, since many women and children as well as men were taken by Iroquois allies and died, were released in dribs and drabs, or remained.Surviving correspondence regarding the missing is in a great many NY manuscript collections which usually mention only one or a few individuals at a time.
If you are looking for information on a particular individual, post the query here.I have independently transcribed some data from the Haldimand Papers and other sources and can do a lookup for NY in particular.
