Michael, >I looked up one of my surnames in the Ancestry 1841 and the 8 people in the census with that name had it spelt in three different ways (two of them mis-transcriptions). The Origins 1841 was 100% correct.< In general I have found Origins transcriptions to be the most accurate - I have forgotten where they are done. Second is 1837Online's 1891 census - much better than their 1861 (which they are improving all the time) - these are done in India. Way down the list comes Ancestry - these are done in China I believe. Ancestry have just spent a lot of time and effort on improving the 1841 images - pity they didn't improve the index!
