Periodically, I've seen references to the Census of September 2, 1771, but couldn't find any lists. The mystery has been solved! Governor O'Reilly ordered a census on September 14, 1769, but it wasn't completed until 1771 [this would explain some differences in ages between the 1766 and 1769 census] The registers were compiled into a report dated September 2, 1771. This is a very interesting report because it shows that the Acadians represented a significant percentage of the total population. The census is in the Annual Report of the American Historical Association 1945 in four volumes, Volume II, Spain in the Mississippi Valley, 1765-1794, Part I, The Revolutionary Period, 1765 - 1781, edited by Lawrence Kinnaird, p. 196. I've created a pdf file that is linked from my Arrival of the Acadians page at the url below. The direct url is also provided.
