The MacNaught History Centre and Archives (MHCA) has a collection of census records for all of Prince Edward Island organized by lot and royalty. The census records for PEI cover the period from 1728-1911, with some gaps of information. The Prince Edward Island Genealogical Society is a major partner with MHCA and has provided printed transcripts for the 1881, 1891 and 1901 census records. Its website www.peigs.ca offers an index by surname. Researchers at MHCA can also view the original handwritten census on microfilm for the years 1841, 1861, 1881, 1891, 1901 and 1911.
