Hello Bob; I can't give you an estimate on how many people were missed on any given census. I can tell you this though, if you are sure that they are in the given area during the time of a census, it might take a page by page search of the images to find them. I recently was looking for several families, and knew they were in a particular area, and hadn't left it. Neither autogenealogy/archives canada/ancestry indexing had them. It took a page by page search of the area to finally discover them. They were there and under their own names spelled correctly. Everyone had missed the boat on transcribing the names correctly. Thank heaven the eneumerator didn't miss them. Happy hunting Juanita MacDonald ----- Original Message ----- From: "bob gillis" <robertgillis@verizon.net> To: "Cape Breton" <ns-cape-breton@rootsweb.com> Sent: Wednesday, February 25, 2009 9:02 AM Subject: [NS-CB] Gillises missing from Census > My great uncle was Alexander Gillis was born Parish of Harris in Dec > 1840.
