The McCulloch Heritage Centre in Pictou, Nova Scotia is starting to put their photographs and collections of historical significance to family history, with emphasis on the arrival of the Scots in 1773, online. The page is titled Find Your Scottish Roots.
If you go to their site at http://www.mccullochcentre.ca/, and log in, you will see where they have started already to put on wills, photos, and there is lots more to come. Census records, diaries, photographs, wills, deeds and newspapers will be added in the future.
