I found the following questions from Lauren intriguing. Is there an 1851 census for Boularderie (or anywhere?). I found 1838-41 and then, 61-91. Also, for the 1871 census for example, it lists dwelling number and family number, Is there anyway to tell where on the island this dwelling is? It is broken into district E1 and E2 also. Since there were no on-line replies, I assume she was replied to directly but still the topic has merit. Here are some thoughts... Censuses are interesting things. The 1841 Cape Breton census seems to have two parts - the census and a census of squatters. The latter has a map associated with it (at the Highland Village). Only bits and pieces of the 1851 census survive. Each of the later censuses had a number of schedules attached, these schedules included information on location, land, crops, livestock and/or income, buildings, etc. The completeness of these schedules varies. For example, the 1911 census in the Vancouver area: for the district identified as Vancouver it gives Street name and address (and sometimes apartment number) but in the district identified as South Vancouver all that is reported is family number and 'South Vancouver' although sometimes a street is named.... On the original films of early British censuses each sub-district is prefaced with a description, including which roads were included... Many on-line transcriptions are incomplete - the easiest found free 1881 Inverness County census (from that site in california) is missing the entire Margaree, Whale Cove area. Another from the same site has much duplication... I guess the point is that if you think you have found someone in a transcription but need more information only the original documents may contain it. Also, some sites like ancestry, only have some of the schedules available - get them from the archives....
