Susanne - The National Archives has listings of all postmasters (Mistresses) on microfilm. I copied the one for Pine Bush, NY since a couple of ancestors were there. I don't know how you can do it by remote action - but the .edu indicates some degree of creativity!. I did a list on Orange Co Postmasters which states: "COMPILED FROM U.S. NATIONAL ARCHIVES MICROFILM 1131, ROLL 1" My list of the Pine Bush PMs cites the following: "Record of Appointment of Postmasters, October 1789 - 1832: Microfilm M1131: National Archives Record of Appointment of Postmasters, 1832 - 30 Sep. 1971: Microfilm M841, Reel 89: National Archives Official Registers of the United States, 1817 - 1911 (Proceeds and Salaries): National Archives (Information reported was received from Ms. Megaera Harris, Postal Service Historian via telecon 09 Feb. 1995, F.W.Sloat) Mr. Hecht's lists - National Archives - received from Ms. Aloha P.
