Hi Arthur As a CGRS I have been doing genealogy since 1969 and my specialty is Hillsbo- rough County. From a published research handbook I quote: Dunstable, part of the Old Dunstable grant made by MA 16 Oct 1673. Inc. 1 Apr.1746. "One Pine Hill" belonging to Dunstable was annexed to Hollis 13 Dec 1763. The farms of Daniel Merrill & Ebenezer Jacquith were taken from Dunstable and annexed to Hollis 14 May 1773. The name was changed to Nashua 8 Dec. 1836." As you can see it is highly likely that any family in Dunstable, NH is "now" in Nashua, NH. Be informed that a separate entity called Nashville, NH broke off in June 1842 but re-united with Nashua June 27, 1853. Hope this helps.
