When I first started doing genealogy in the late 80's I was given a copy of a will for my 4th great-grandfather. Notes written on the copy indicate that the will came from the Historical Documents Collection at Queens College. From what I can read of the title it appears to be Albany Court of Pro___ Wills, no. AG44. At the Queens College Library website you find the following statement "The Library no longer holds the Queens College Historical Document Collection" they further state "The library has no records of the current location of any items formerly held in this collection." There is also a link to the New York State Archives.
Just recently FamilySearch uploaded a collection, New York, Probate Records, 1629-1971. This collection is browse only. Eventually I found the will and the FHL film number 481439. Going to the catalogue the authors are listed as New York Surrogate's Court (Albany County) and Albany County (New York) Clerk of the Court of Appeals. In the notes section is the following "Microfilm of original records at the Queens College Library in Flushing, New York."
The New York State Archives has a research tool, "Probate Record Pathfinder" following this tool brings you to a link J0038-82 with the note, Arranged alphabetically by testator, then numerically by file number. This description follows the number on the copy I have and the images from FamilySearch. The first image is of a file folder with the following Gilchrist, Alexander of Argyle Charlotte Co. 29 July 1784 AG44.
Following the link at the NYS Archives viewing the details the title is Probated wills, 1665-1815, New York (State) Court of Probates. Pages 34.5 cu. ft. The catalog record lists copies 11 microfilms.
Comparing the number of microfilms in the FHL collection and the state archives and the descriptions of each. It appears that at least part of the Historical Documents Collection from Queens College is now housed at the NYS Archives.
For my citation I am planning on using the FHL microfilm, the scans are better than the copy of the original I have. Since it took many hours to figure out what happened to this collection I think it is important to make some kind of note in the citation as to where the originals are currently located and that the Historical Document Collection no longer exists. I have been unable to determine the date that the collection at Queens College was dismantled.
Have I determined where the original documents are located? Do I need more evidence that I have located the originals?
